Divide and write in simplest form 2 1/7 divided by 1 1/4
stich3 [128]

Hi!

<h3>To divide a fraction, you multiply by the reciprocal of the second fraction. </h3><h3>First, convert the mixed numbers to fractions, by multiplying the denominator by the whole number and adding that to the numerator. </h3>

---------------

2 * 7 = 14

14 + 1 = 15

15/7

---------------

4 * 1 = 4

4 + 1 = 5

5/4

---------------

<u>\frac{15}{7} * \frac{4}{5} = \frac{60}{35} (simplify) = 1 \frac{5}{7}</u>

<h2>The answer is 1 5/7 </h2>

Hope this helps! :)

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover
grigory [225]

Answer:

I think it's 1 1/4 liters of paint for one door

Step-by-step explanation:

First you have to turn it to an improper fraction

1.) 1 3/5 = 8/5

Then you have to proportion the fraction with the 2 liters (L=liters)

2.) 2/(8/5)

= 10/8 L

3.) Next you convert the fraction to a mixed number

10/8 L --> 8/8 + 2/8 = 1 1/4 L
