Matthew used 1/5 of a box of flour for cooking and 3/4 of the remainder to make bread. The rest of the flour was packed equally into 5 containers. What fraction of the total amount of flour was in each container?

Answers

Matthewused 1/5 of a box of flour for cooking.
=> Let’s convert this to decimals.
=> 1/5 = 0.2

Next, ¾ of the flour remainder is for the making bread
=> ¾ = .75

The rest are equally divided into 5 containers. Now, we need to find the totalamount of flour used in each container.
=> Let’s add first the first 2 fractions converted to decimals.
=> 0.2 + .75 = 0.95
=> 1.00 – 0.95 = 0.05
=> 0.05 / 5 = 0.01 => total amount of flour in each container.





If you would like to know what fraction of the total amount of flour was in each container, you can calculate this using the following steps:

used 1/5 of a box of flour for cooking:
1 - 1/5 = 5/5 - 1/5 = 4/5 remained
3/4 of the remainder to make bread:
4/4 - 3/4 = 1/4
1/4 of 4/5 = 1/4 * 4/5 = 1/5 of the box of flour remained

packed equally into 5 containers:
1/5 / 5 = 1/5 * 1/5 = 1/25 of the box of flour was put into each container

Result: 1/25 of the total amount of flour was in each container.

What is the solution to 4w=2/3

Answers

2/12 or 1/6. You have to divide 2/3 by 4 to get what w equals to.
4w = 2/3 Divide each side by 4 to get w by itself.

w = 2/3 ÷ 4 To divide fractions you multiply the reciprocal

w = 2/3 × 1/4 multiply across

w = 2/12 which reduces

w = 1/6
