Question

1) Using appropriate properties find the following.



-3/4 x 4/5 + 7/2 - 4/6 x 1/7​

Answer 1

Answer:

589/210

Step-by-step explanation:

According to bodmass we must multiple first

so, -3/4 × 4/5 in this 4 and 4 are cancelled

so now its -3/1 × 1/5 now we multiple it

-3 × 1. -3

_ _. = _

1 5. 5

now the equation is -3/5 + 7/2 - 4/6 × 1/7

we multiple -4/6 × 1/7 as we have done

and the answer will be -2/21

Equation is -3/5 +7/2 - 2/21

now we add - 3/5 + 7/2

we need to take LCM first the LCM of there denominators will be 10

and it will be -6/10 + 35/10

we add now ans. 29/10

equation will be 29/10 - 2/21

we subtract them and have 589/210
