Question

a) 10% more than 300
And
b) 20% less than 800

Answer 1

Answer:

1. 30
2. 160

Step-by-step explanation:

10%of 300 = [(300/100)*10] = 30

20% of 300 = [(800/100)*20] = 160

Answer 2

• a) $\longrightarrow \: 300 +( 30 \cancel0 \times \frac{1 \cancel0}{1 \cancel0 \cancel0} ) \\ \longrightarrow \:300 + 30 = 330$
• b) $\longrightarrow \: 800 - ( 80 \cancel0 \times \frac{2 \cancel0}{1 \cancel0 \cancel0} ) \\ \longrightarrow \:800 - 160 = \red{640}$
