Write a division problem that has a 3 digit dividend and a divisor between 10 and 20

posledela

Dividend means the number to be divided, the divisor is the number you divide with.

It sounds like you just need to divide a three-numbered integer by a number between 10 and 20.

Example: Dividend --> 333÷16 <-- Divisor

2/3 times what equals 10?

Aleks [24]

You have to divide 10 by $\frac{2}{3}$

$\frac{10}{1}$ ÷ $\frac{2}{3}$ ⇒ $\frac{10}{1}$ x $\frac{3}{2}$

You use a method called "flip-flop and multiply" where you flip the second fraction to multiply
$\frac{10}{1}$ × $\frac{3}{2}$ ⇒ $\frac{30}{2}$

Now divide the numerator (top) by the denominator (bottom)

$30
$ ÷ $3=15$

Now lets check:

$\frac{2}{3} * \frac{15}{1} = \frac{30}{3}$

$30$ ÷ $3=10

$

Answer: $\frac{2}{3}$ × $15=10$

The answer would be B because the sum of the squares of the 2 shorter sides equal the square of the longer side, which is the pythagoream theorem of a^2+b^2=c^2.
