Question

Find the value of -4/15 + 7/10 + 3/5.

Answer 1

Step-by-step explanation:

1st make the denominator common with the help of equivalent property using lcm

so LCM OF 15 ,10,5 is 30

so

$\frac{ - 4 \times 2}{15 \times 2} = \frac{ - 8}{30} \\ \frac{7 \times 3}{10 \times 3} = \frac{21}{30} \\ \frac{3 \times 6}{5 \times 6} = \frac{18}{30} \\ \\ so \frac{ - 8 + 21 + 18}{30} = \frac{21 + 10}{30} = \frac{31}{30}$

Answer 2

Answer:

31/30

Step-by-step explanation:

-4/15 + 7/10 + 3/5

= -8/30 + 21/30 + 18/30

= 31/30

=

$1 \times \frac{1}{30}$
