Answer:

8/15

Step-by-step explanation:

the denominators are different so you need to find the lowest common multiple which is 15

you times 3 by five so you have to change the 1 into 5

you times 5 by three so you have to change the other numerator to 3

so it becomes:

5/15 + 3/15= 8/15

Three students are from a plate of cookies.Daniel ate 1/12 of the cookies, Mariel ate 4/12 of the cookies, and Tamika ate 2/12 o
Mrac [35]

Answer:

5/12  of cookies left on the plate

Step-by-step explanation:

we have to add to know what part of the dish ate and then subtract it from the total

1/12 + 4/12 + 2/12 =

when we are adding fractions with the same denominator we simply add the above

1 + 4 + 2 = 7

1/12 + 4/12 + 2/12 = 7/12

now to the total of the plate that would be 1 we subtract what they ate

1 - 7/12 =

the whole 1 can be expressed as 12/12 since if we do the 12/12 = 1 account

12/12 - 7/12

for the subtraction with the same denominator the same thing happens as for the sum, we only do it with the top

12 - 7 = 5

12/12 - 7/12 = 5/12

X=25
50 times 25=y
50*25=1250
y=1250 mm cubed this is the volume of the stack of 50
