Ms Singh wants to buy a new television that costs £840
amm1812

Cost of a television Ms. Singh wants to buy = £840

Ms. Singh's weekly wage = £300

Money she saves each week :

= 40% of her weekly wage

=\tt 40\% \: of \: 300

= \tt \frac{40}{100} \times 300

=\tt  \frac{40 \times 300}{100}

=\tt  \frac{12000}{100}

\color{plum} = \tt£120

Thus, Ms. Singh's weekly savings = £120

Number of weeks in which she will be able to buy a TV :

= \tt \frac{840}{120}

\color{plum} =\tt 7 \: weeks

Therefore, Ms. Singh will be able to buy a TV from her savings in <u>7 weeks</u>.

The school wants to build a new sandbox for the grade R playground the sandbox must be 4m long 3m wide and 0,5m high
Daniel [21]

The new dimensions of the sandbox in centimeter (cm) are:

length = 400 centimeters

Width = 300 centimeters

Height = 50 centimeters

Given:

Length = 4m

Width = 3m

Height = 0.5m

Convert meter to centimeter

1 meter = 100 centimeters

4m = 4 × 100 centimeters

= 400 centimeters

3m = 3 × 100 centimeters

= 300 centimeters

0.5m = 0.5 × 100 centimeters

= 50 centimeters

Therefore, the new dimensions of the sandbox in centimeter (cm) are

length = 400 centimeters

Width = 300 centimeters
