Question

$\text{Sarah needs}4\frac{3}{5}\text{cups of flour to make 1}$
$\text{apple pie. If she makes}10\text{apple pies, how}$
$\text{many cups of flour does Sarah need?}$

• A. 46
• B. 48
• C. 51
• D. 49

Answer 1

The correct option is A 46

Amount of flour used for 1 apple pie = $4\frac{3}{5}$

If Sarah makes 10 apple pies.

$\text{∴ Number of cups of flour needed =}10\times 4\frac{3}{5}$

Now,
$10\times 4\frac{3}{5}=(10\times 4)+10\times \frac{3}{5}$

$=40+\frac{10\times 3}{5}$

$=40+\frac{30}{5}$

$(Now,30=5+5+5+5+5+5)$

So,


$\text{∴ Sarah needs}46\text{cups of flour to make}$
$10\text{apple pies}.$
