3 times as much :-)

Convert each mixed numeral into an improper fraction, then multiply by 3/1.

whpalmer4 · Answer

You could approach this at least 2 different ways:

1) addition
2) multiplication

Addition: to make 3 batches of the recipe, add each amount 3 times.  For example the flour would be 2 1/3 + 2 1/3 + 2 1/3 = 6 3/3 or 7 cups.

Multiplication: multiply each amount by 3.  3*2 1/3 = 3*2 + 3*1/3 = 6+1 = 7

What do you get for the amount of sugar?

not that the problem asks, but it's generally preferable when baking to measure flour by weight...
