A shop only sold black, blue and green sweaters.
712 of the sweaters in the shop were green and 63 sweaters were blue. If
18 of the sweaters were black, how many sweaters were there in the shop?
Fraction of the sweaters that were blue
= 1 -
712 -
18= 1 -
1424 -
324=
724
Total number of sweaters = 24 u
Number of sweaters that were blue = 7 u = 63
= 63 ÷ 7
= 9
Total number of sweaters
= 24 u
= 24 x 9
= 216
