36) Thursday, 1400 or 2 p.m.
37) $400
38) Aminah's red beads - 24
Total for Jane - 40
39) 5/9
40) Yes, No, No, No

41) $1.20

42) 1/5 + 7/10 = 9/10
(a) 9/10
1 unit-> 6
10 units -> 60
(b) $60

43) 1.45 x 2 = 2.9
4.2 - 2.9 = 1.3
Ans: 1.3km

44) 7 x 4 = 28
length of larger area -> 7 + 2 = 9
breadth of larger area -> 4 + 2 = 6
9 x 6 = 54
54 - 28 = 26
2
Ans: 26 m

45) 3 x 2.50 = 7.50
23.10 - 7.50 = 15.60
1.40 + 2.50 = 3.90
15.60 ÷ 3.90 = 4 (there are 4 groups of 1 pen and 1 pencil)
4 + 3 = 7

Ans: 7 pens

Using Guess and Check:

Number of Pens Number of pencils Total Cost Check
4 1 ( 4 x $2.50) + (1 x $1.40) = $11.40 x
5 2 ( 5 x $2.50) + (2 x $1.40) = $15.30 x
6 3 ( 6 x $2.50) + (3 x $1.40) = $23.10 ⁄
