Question

Jenny has $3\frac{2}{3}$ part of a cake as shown. How many slices of cake does she have in total?
(Given each cake has three slices)

• A. 9
• B. 10
• C. 11
• D. 12

Answer 1

The correct option is C 11

Given each cake has three slices.

3 full cakes and two-third of cakes will have
$3+3+3+2=11$ slices

Hence, a total number of slices = 11

Alternative method: Convert $3\frac{2}{3}$ into its mixed fraction

Step 1: Multiply the denominator "3"(the bottom number in the fraction) and the whole number "3"

$3\times 3=9$

Step 2: Add the answer from Step 1 to the numerator "2"(the top number in the fraction)

$9+2=11$

Step 3: Write answer from Step 2 over the denominator "3"

$\frac{11}{3}$

$3\frac{2}{3}=\frac{11}{3}$ as numerator is 11 so the number of slices will be 11.
