Name:
A Number Sentence is an arrangement of numbers and symbols.
E.g. 117 x 23 = 2691
1. Fill in the gaps in the following number sentences:
(a) 145 – __ = 120
(b)25 + __ = 100
(c) __ + 55 = 100
(d)100 – __ = 35
(e) 16 x __ = 160
(f ) 1000 – 2 = __
(g)(g) 108 ÷ __ = 12
(h)600 ÷ 30 = __
2. Sometimes you need to change a normal sentence into a number sentence:
e.g. Multiply 9 and 2 and then subtract 13
(9 x 2) – 13
Now you try! (You don’t need to solve the number sentence):
(a) Find the product of 2 and 3 then take that from 8.
(b)Multiply 2 by the product of 8 and 9.
(c) Find 4 more than 8 minus 3
(d)Add 2 and 5 and then divide 7 by the sum.
(e) Subtract 5 from 13 and then divide the difference by 4.

Answers
(a) Seven shirts cost R350.00. What is the cost of 12 shirts?
(R350.00 ÷ 7) x 12
= 50 x 12
= 50 x 10 x 2
= R1000.00
Clue Board:
7 x 5 = 35
7 x 50 = 350
(b)Penny bought a magazine for R12.50 and a newspaper for R5,00. She paid
with a R50.00 note. How much change did she get?
R50.00 – (R12.50 + R5.00)
= R50.00 – R17.50
= R32.50
To make one lot of pancakes you need 750ml milk. How much milk is needed
if you want to follow a recipe four times?
750ml x 4
= (700 x 4) + (50 x 4)
= 2800 + 200
= 3000ml
(c) There are 25 oranges in a bag. How many oranges are in 20 bags?
25 x 20
= (20 x 20) + (5 x 20)
= 400 + 100
= 500 oranges
