Question

Kaylin mixed two liquids for a science experiment. One container held 7/8 cup and the other held 9/10 cup.what is the total amount of the mixture

Answer 1

71/40

Explanation:

We find the common denominator, which is 40,

so the first numerator is 9x4, and the second numerator is 7x5,

and adding them we get 71

and so the answer is numerator/denomitar = 71/40

Answer 2

• 1 31/40 cup

Explanation:

Add up the volumes to find the volume of the mixture:

• 7/8 + 9/10 =
• 5*7/5*8 + 4*9/4*10 =
• 35/40 + 36/40 =
• 71/40 =
• 1 31/40 cup
