Dakota and Howie went out for pizza. Dakota ate 1/4 of the pizza
Howie ate 3/5 of the pizza.
How much did they eat together

17/20 of the pizza.

Step-by-step explanation:

First, we need to give these two fractions a common denominator, to do this, we need to find the LCM of 4 and 5. The LCM of 4 and 5 is 20. Now, we multiply 1/4 by 5/5 and mulitply 3/5 by 4/4. When we do this, we get 5/20 and 12/20. Now, we add those fractions and simplify (if we can). When we add them (don't add the bottom numbers), we get 17/20. We can't simplify this, so we just leave it as it is. I hope this helped!

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

answer is 33
