A zookeeper is 6 and 1/4 feet tall A young giraffe in his care is 9 and 3/8 tallHow many times as tall as the zookeeper is the giraffe? ​
can some one help
Are you able to convert from mixed numbers to improper fractions?
yes
what does 6 & 1/4 convert to?
25/4
correct
how about 9 & 3/8?
and 9 and 3/8= 75/8
also correct
so what we need to do is solve for x in the equation (25/4)x = 75/8
um im confused
To start things off, I would multiply both sides by 8 to clear out the fractions (25/4)x = 75/8 8*(25/4)x = 8*75/8 2*25x = 75 50x = 75 What's the next step?
what do u mean by this 25/4)x = 75/8
im still confused can you break it down easier
I'm multiplying the person's height by x to get the giraffe's height
Just as a simpler example Let's say the person was 6 ft tall and the giraffe was 12 feet tall This would lead to the equation 6x = 12 which solves to x = 2 when we divide both sides by 6. x = 2 means the giraffe is 2 times taller compared to the human
ohh💆
Hopefully that makes more sense now?
yup
ok great
whats next
So we'll use the same idea for 50x = 75
what must we divide both sides of 50x = 75 to isolate x?
0.66
i think
im not quite sure
50x means 50 times x we need to undo that multiplication of 50
Going back to 6x = 12, I divided both sides by 6 To solve 50x = 75, we need to divide both sides by _____
1.5
helloooo UWU
no, we'll divide both sides by 50
|dw:1606867302746:dw|
|dw:1606867318573:dw|
|dw:1606867346612:dw|
so we divide 75 and 50 and 50 and 50
yes and the 50/50 cancels out as my drawing shows
so you just need to determine what 75/50 is equal to
do you mean the fraction 75/50
yes you'll need to convert the fraction 75/50 into a mixed number
1 25 50
or to minimize it would be 1 1 2
then what does 25/50 reduce to?
yes you beat me to it
75/50 = 1 & 1/2
ok so is the answer 1 1/2
yes 1 and a half
says incorrect tho
i have another problem just like this one
try 3/2 if it doesn't like 1 & 1/2
and you could also try 1.5 3/2 = 1 & 1/2 = 1.5 they are all different ways of saying the same thing
incorrect still
I'm not sure then. It's probably a typo. I would ask your teacher to look into it.
ok i have another question just like this one sorry to bother you 🤗
no worries, go ahead
ok one sec
A rectangular bathroom floor is covered with square tiles that are 1and 1/2 feet by 1 and 1/2 feet the length of the bathroom floor is 10 and 1/2 feet and the width is 6 1/2 feet .ow many tiles does it take to cover the width of the floor?
there
hello idk if your still there
hello UWU
yes I'm reading it over
oh ok sorry
1 & 1/2 converts to 3/2 6 & 1/2 converts to what improper fraction?
13/2
Actually it might be easier to use decimals here 1 & 1/2 = 1.5 6 & 1/2 = what decimal number
6.5
yes so if x is the number of tiles along the width, then 1.5x = 6.5 is the equation we need to solve
can you draw it out im a visualizer
sure I'll give a similar example
Let's say each tile was 2 inches wide And let's say we have a very small room that is 12 inches (1 foot) wide This is what the drawing would look like |dw:1606868821932:dw| That drawing shows how the solution to 2x = 12 is x = 6 In other words, we need 6 tiles along the width of the room.
ok
whats next
So we need to solve 1.5x = 6.5
to do so, divide both sides by _____
