Answer 1

Answer:

D

Step-by-step explanation:

(3.25+4.75+15) =23

23- (2.5+2.75+10)

= 7.75

Answer 2

Millet: convert 2 1/2 to 4ths, and 3 1/4 to an improper fraction as well

2 1/2 = 5/2 = 10/4
13/4 -10/4 = 3/4 kg of millet left over

Sorghum:
4 3/4 - 2 3/4 = 2 kg of sorghum left over

Maize:
15kg - 10kg = 5kg left over

3/4 + 2 + 5 = 7 3/4 kg total
