Angie and her friends are 3 4ths of a pizza. her brother joe ate 2 3rds of what was left. how much of the original pizza did joe eat?

The brother ate 1/6

Step-by-step explanation:

3/4 = 9/12

The whole pizza is 12/12

12/12 - 9/12 = 3/12

3/12 is what is left

The broter ate 2/3 of this  leftover

3/12 = 1/12 +1/12 + 1/12

the brother ate 2/12  =   1/6

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

4x and 6y

im not sure though
