Question
While taking inventory at her pastry shop, Valentina realises that she had 1/2 of a box of baking powder yesterday, but the supply is now down to 1/3 of a box. How much more baking powder did Valentina have yesterday?Write your answer as a fraction or as a whole or mixed number.
Solution
Valentina had 1/2 of a box of baking powder yesterday and now she has 1/3 of a box. To find out how much more baking powder she had yesterday, you subtract the amount she has now from the amount she had yesterday.
Step 1: Convert the fractions to have the same denominator. The least common denominator between 2 and 3 is 6. So, convert 1/2 to 3/6 and 1/3 to 2/6.
Step 2: Subtract the fraction representing the current amount of baking powder (2/6) from the fraction representing the amount of baking powder she had yesterday (3/6).
3/6 - 2/6 = 1/6
So, Valentina had 1/6 more of a box of baking powder yesterday.
