How long does it take the clerk to process 1 application?
4.A bulldozer moves 640 lb of dirt in 4/5 h.
Complete the unit rate.
5.A contractor takes 4 1/2 days to build 3/4 of a deck.
Complete the unit rate.

Answer 1

1) It contains 3 oz, and is 1/6 full. So when it is full it contains \[3*6=?\]

Answer 2

@Tommynaiter is 18oz the answer to #1

Answer 3

Yes, that is correct.

Answer 4

@ShiBuringa @Lexi_Loves Help???

Answer 5

2) She can chop 3/4 in 1/8 min. So we need to find how long it takes to chop a full carrot. So you need to multiply the time with 4/3 because: \[\frac{3}{4}*\frac{4}{3}=1\]
So you get: \[\frac{1}{8}*\frac{4}{3}=?\]

Answer 6

3) If it takes 3/4 h, to do 9 applications, then you need to divide the time with 9 to get the time it takes to do 1 application. \[\frac{3/4}{9}=?\]

Answer 7

So is #2 1/6

Answer 8

And #3 1/12

Answer 9

Answer 10

@iGreen

Answer 11

2) Is correct, 1/6.
3) is correct, 1/12

Answer 12

Thanks

Answer 13

What about 4 and 5 do you mind helping with those

Answer 14

4) It moves 640 lb in 4/5 h. How much does it move in 1 hour? You need to find how much you have to multiply 4/5 to get 1. This is just like 2).

Answer 15

\[\frac{4}{5}*\frac{5}{4}=1\]
Now multiply 640 with 5/4

Answer 16

It is the same for 5), figure out how much you need to multiply to get 1.
