The ratio of the quantities of sugar and flour needed to bake a cake is 2:5. What is the quantity of sugar needed for a cake, if 750 grams of flour are used to make it?

Is it 300?

good work this help a lot

2/5 = x/750

Solve for x

To find the quantity of sugar needed for the cake, we can use the given ratio of sugar to flour: 2:5.

Step 1: Understand the given information. The given ratio tells us that for every 2 parts of sugar, we need 5 parts of flour.

Step 2: Set up an equation. Let's represent the quantity of sugar needed as 'x', and the quantity of flour used as 750 grams. The equation will be:

2/5 = x/750

Step 3: Solve the equation. Cross-multiply to get rid of the fraction:

5x = 2 * 750
5x = 1500

Divide both sides of the equation by 5:

x = 1500 / 5
x = 300

Therefore, the quantity of sugar needed for the cake is 300 grams.

Does that make sense?
