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?
