If 1/4 of the 7th graders got an A on the test and 2/5 of them got a B, that fraction of the students got an A or B?

posledela

Answer: $\dfrac{13}{20}$

Step-by-step explanation:

Given: Fraction of 7th graders got A = $\dfrac14$

Fraction of 7th graders got B = $\dfrac25$

The fraction of the students got an A or B = Fraction of 7th graders got + Fraction of 7th graders got B

$=\dfrac14+\dfrac25\\\\=\dfrac{5+2(4)}{5\times4}\\\\=\dfrac{5+8}{20}\\\\=\dfrac{13}{20}$

Hence, the required fraction: $\dfrac{13}{20}$
