Question

how would you solve the following math problem 7 7/15-4 4/15 step by step answer is 16/5

Answer 1

You'll have to change this to full fractions (no whole numbers). Here is how you turn what you have (whole numbers + fractions) into just a fraction:

Answer 2

$$7 \frac{7}{15} = \frac{7 * 15 + 7}{15}$$

Answer 3

so doing that for each, it will be easy do simple subtraction...

Answer 4

i thank you so much so after that i just have the answer of 16/5?

Answer 5

$$\frac{7*15+7}{15} - \frac{15*4 + 4}{15} = \frac{112}{15} - \frac{64}{15} = \frac{48}{15} = \frac{16}{5}$$

Answer 6

$$\frac{48}{15} = \frac{16}{5} (reduced)$$

Answer 7

thank you so much for your help

Answer 8

Btw, you reduce it by seeing that 5 is the denominator you want, and you have to divide 15 by 3 to get 5, so dividing both 48 and 15 by 3 gets you 16 / 5.

Answer 9

thank you

Answer 10

great work here!

Answer 11

plz solve this 4 me g is inverse of f f(4)=5,f\[\prime\](4)=2/3,find g\[\prime\](5)

Answer 12

@toni32: if using big numbers is too complicated, you can still use this method.
1st step: subtract the whole numbers: 7 - 4 = 3
2nd step: subtract the fraction: 7/15 - 4/15 directly as they have the same denominator.Ans: 3/15
reducing it to 1/5
3rd step: combine( or add) the whole number with the fraction:
3 + 1/5 = 3 1/5 (as a mixed fraction) or 16/5 (as an improper fraction).
