Answer: 24
Step-by-step explanation:
Amount of bushels of peas collected = 42
Fraction that'll be sent to market = 3/7
Fraction that'll be kept = 1 - 3/7 = 7/7 - 3/7 = 4/7
The number of bushels that'll be kept will be:
= Fraction that'll be kept × Total number of bushels collected
= 4/7 × 42
= 24
The answer would be:
93
+75
