Answer 1

Answer:

$3\dfrac{5}{8}$ pizzas.

Step-by-step explanation:

It is given that Aisha and her friends ate $2\dfrac{1}{2}$ pizzas.

After the party, the remaining pizza is $1\dfrac{1}{8}$ pizzas.

Now,

$2\dfrac{1}{2}=\dfrac{4+1}{2}=\dfrac{5}{2}$

$1\dfrac{1}{8}=\dfrac{8+1}{8}=\dfrac{9}{8}$

Pizzas at the starting = Pizza eaten by Aisha and her friends + Remaining pizza

$=\dfrac{5}{2}+\dfrac{9}{8}$

$=\dfrac{20+9}{8}$

$=\dfrac{29}{8}$

$=3\dfrac{5}{8}$

Therefore, $3\dfrac{5}{8}$ pizzas were there at the start of the party.
