I am a bit tangled up in this question.

I would be extremely grateful if ya all help me understand it.😊

The question is 2/5*-3/7-1/14-3/7*3/5

The solution is :

-3/7*2/5+(-3/7)*3/5-1/14

=-3/7*(2/5+3/5)-1/14

=-3/7*5/5-1/14

=-3/7-1/14

=(-6-1)/14

=-7/14

=-1/2

I know that the kind ones will help me:)😄

Ok, so first lets group what we have to do first. This question would be grouped as (2/5*-3/7) - 1/14 - (3/7* 3.5) First solve the parenthesis. 2.5 * -3/7 = a. then solve 3/7*3.5=b. so you would keep it as a- 1/14 - b. That would be the answer. I don't want to give the answer away completely, so I'm using variables to help you understand completely.
