What is bigger, 29/40, 7/10 or 3/5
Romashka-Z-Leto [24]
Place each fraction under a common denominator. Remember, the number you multiply to the denominator must also be multiplied to the numerator

29/40 = 29/40
7/10(4/4) = 28/40
3/5(8/8) = 24/40

As seen by the fractions above, the order is 24/40, 28/40, and 29/40, <em>or</em> placed in it's original form is 3/5, 7/10, 29/40.

29/40 is the greatest, and is your answer

There are 7 boxes stacked on the floor in the math department supply closet. Each box has a height of 10 inches or 8 inches. The
Orlov [11]

Answer:

5 of the 7 boxes are 8 inches in height

Step-by-step explanation:

Mathematically;

1 ft = 12 inches

So, 5 ft will measure 5 * 12 = 60 inches

So from what we have ,

We want to combine 8 and 10 inches to give 60 inches total

Let the number of 10 inches be x and the number of 8 inches be y

Mathematically;

x + y = 7 •••••(i)

10x + 8y = 60 ••••(ii)

From equation i, x = 7-y

Put this in equation ii

10(7-y) + 8y = 60

70-10y + 8y = 60

70-60 = 10y-8y

2y = 10

y = 10/2

y = 5
