M1
Use multipliers to perform these calculations
a) Increase £235 by 21%
121% = 1.21
1.21 x 235 = £284.35
b) Decrease £1120 by 13%
87% = 0.87
0.87 x 1120 = £974.40
121% = 1.21
1.21 x 235 = £284.35
b) Decrease £1120 by 13%
87% = 0.87
0.87 x 1120 = £974.40
c) Increase 24 grams by 7%
d) Decrease 0.057 by 57%
