Zeph had 280 pens. He gave
58 of it to Paul and
45 of the remainder to Lucy. How many pens had he left?
Fraction of the pens left after giving to Paul
= 1 -
58 =
38 Fraction of the remaining pens left after giving to Lucy
= 1 -
45 =
15
Fraction of the pens left after giving to Paul and Lucy
= 38 x 15
= 340
Total number of pens = 40 u
40 u = 280
1 u = 280 ÷ 40 = 7
Number of pens left
= 3 u
= 3 x 7
= 21
