WebWe need to determine how many shares there are in the ratio overall. We do this by adding the parts of the ratio together, 2+3=5 2 + 3 = 5 shares. We have £10 £10 being split into 5 5 shares, and so we divide the quantity by the total amount of shares of the ratio 10 \div 5=2. 10 ÷ 5 = 2. We call this the value of one share. WebRatios can have more than two numbers! For example concrete is made by mixing cement, sand, stones and water. A typical mix of cement, sand and stones is written as a ratio, such as 1:2:6. We can multiply all values by the same amount and still have the same ratio. 10:20:60 is the same as 1:2:6 WebFeb 9, 2024 · 7 x = 17500. x = 2500. The value x represents what you have to multiply each of the values in the ratio by. Now to solve, we multiply the corresponding number by the multiplier to get the actual amount of students. Boys = 4 × 2500 = 10000. Girls = 3 × 2500 = 7500. This is correct since if you add the two amounts together, you get 17,500 students. lowes mister kit
