Marie wants to make lemonade. She buys lemons and sugar. She uses 0.9 lemons and 0.25 sugar

What units of measurement is she using?

decimals?

cups? liters? quarts?

i think its that you are to just mulitpy the decimals

No way. That makes no sense.

To find out how much Marie uses in total, we need to add the quantities of lemons and sugar.

Marie uses 0.9 lemons and 0.25 sugar.

To add these numbers, simply add the decimal values:

0.9 + 0.25 = 1.15

Therefore, Marie uses 1.15 units in total.
