For every £1.00 a company spends on advertising, it spends £0.75 on its website. Express the amount spent on advertising to the amount spent on its website as a ratio in its simplest form.

4:3

Step-by-step explanation:

For every £1.00 a company spends on advertising, it spends £0.75 on its website.

From the above question:

The ratio is given as:

Amount spent on advertising : Amount spent on website

= £1.00 : £0.75

Convert ratio sign to division

= 1/0.75

Multiply Numerator and Denominator by 100

= 1 × 100 / 0.75 × 100

= 100/75

= 4/3

= 4 : 3

Therefore, the ratio in its simplest form = 4:3

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
