2 2/3
1 4/7

Answered by admin @ 22/11/2021

Answer:

$2\frac{2}{3}$ = $\frac{8}{3}$

$1\frac{4}{7}$ = $\frac{11}{7}$

Step-by-step explanation:

$2\frac{2}{3}$

To convert a mixed number to an improper fraction all you need to do is......

Multiply the denominator of the fraction (3), by the whole number (the big number in front of the fraction) (2), and then you add the numerator....

Denominator times the whole number ( 3 * 2 = 6)

Now add the numerator with what you got ( 6 + 2 = 8)

Now the "8" will be the new numerator, and the denominator stays the same "3".

Improper fraction: $\frac{8}{3}$

__________________________________________________________

$1\frac{4}{7}$

We can do the same steps we did for the one above

Multiply the denominator (7) by the whole number (1), and then add the numerator (4)....

Denominator times whole number ( 7 * 1 = 7)

Add the numerator to the answer you got ( 7 + 4 = 11)

Now "11" will be the new numerator, and the denominator stays the same "7".

Improper fraction: $\frac{11}{7}$

Hope this helped!
