The answer is A, first you get a common denominator so 72. So they become 27/72 x 32/72 = 12/72 or 1/6. Then when you go through the answers you multiply 4/8 by the number of groups and divide by equal parts until you get 12/72. The answer is A because 4/9 x 3 is 1 3/9 divided by 8 = 12/72.

A pancake recipe require 1 2/3 cups of flour to make 20 pancakes and you have 9 cups of flour.

Leokris [45]

<h2>Solution (a) :-</h2>

Quantity of flour needed to make 20 pancakes =

$= 1 \frac{2}{3} \:$

$= \frac{3 \times 1 + 2}{3}$

$= \frac{5}{3} \: cups \: of \: flour$

Then , number of pancakes that can be made from 1 cup of floor :-

$20 \div \frac{5}{3}$

$20 \times \frac{3}{5}$

$\frac{60}{5}$

$= 12 \: pancakes$ .

Therefore , 12 pancakes can be made from 1 cup of floor .

<h2>Solution (b) :-</h2>

Number of pancakes that can be made with 1 cup of flour = 12 pancakes

Number of pancakes that can be made with 9 cups of flour :-

= 9 × 12

= 108 pancakes

Therefore , I can make 108 pancakes with 9 cups of flour .

<h2>Solution (c) :-</h2>

Yes , I have enough flour to make 100 pancakes . I say this because :-

With one cup of flour I can make = 12 pancakes

With 9 cups of flour I can make =

= 9 × 12

= 108 pancakes

As I can make 108 pancakes with 9 cups of flour , I can conclude that I have enough flour to make 100 pancakes .
