During a home science lesson,grade 8 learners mixed sugar and wheat flour in the ratio respectively. If they used 40 grams of sugar, what was the mass of the wheat flour used
Let's set up a ratio with the given information:
Sugar : Wheat Flour
We know that the ratio is 1:1, meaning that for every 1 part of sugar, there is 1 part of wheat flour.
Since they used 40 grams of sugar, we can set up a proportion to find the mass of the wheat flour:
1 part of sugar : 1 part of wheat flour :: 40 grams : x grams
1/1 = 40/x
Cross multiply:
1*x = 1*40
x = 40
Therefore, the mass of the wheat flour used was 40 grams.
