Question

Mandy had $1600 at first. She spent 2/5 of the money on a computer and spent another 1/8 of it on a present for her mother. She donated 1/10 of the renaming money and saved the rest. 

(a) What fraction of her money did Mandy spend on the computer and the present? 

(b) How much money did Mandy save? 

Source: South View Primary

Answer

Alternatively,

(a)
2/5 + 1/8 = (16 + 5)/40 = 21/40
or
(2/5) x 1600 = 640 (computer)
(1/8) x 1600 = 200 (present of her mother)
200 + 640 = 840
840/1600 = 21/40

(b)
1600 – 840 = 760

1 – (1/10) = 9/10
(9/10) x 760 = 684
or
(1/10) x 760 = 76 (donated)
760 – 76 = 684

Ans : (a) 21/40; (b) $684.
