Three hundred fifty pounds of sugar were poured into 4 38 po
Solution
Answer 17
Capacity of one packet = 4 3/8 pounds = 35/8 pounds
Total quantity of sugar available = 350 pounds
Therefore, total number of packets required to fill 350 pound sugar
= (Total quantity of sugar available)
( Capacity of one packet )
= 350
( 35/8 )
= 350 * 8
( 35 )
= 80 packets
Answer 18
Capacity of one can = 2 3/4 gallon = 11/4 gallon
Total quantity oil available in a tank = 90 3/4 gallon = 363/4 gallon
Therefore, total number of cans required to fill 363/4 gallon oil
= (Total quantity of oil available)
( Capacity of one can )
= ( 363/4 ) / ( 11/4 )
= 363 / 11
= 33 cans
Answer 19 (A)
( 5/8 ) / 5
= 5 * 5
( 8 )
= 25 / 8
= 3.125
Answer 19 (B)
= ( 45 )
( 3 3/4 )
= ( 45 )
( 15/4 )
= 45 * 4
( 15 )
= 180 / 15
= 12
Answer 20
= ( 3/4 + 5/8 ) / ( 3/4 - 1/2 )
= [ {3(2) + 5} / 8 ] / [ 3 - 1(2) / 4 ]
= ( 11/8 ) / ( 1/4 )
= ( 11 * 4 )
( 8 * 1 )
= 44 / 8
= 11 / 2
= 5.5
