-4/7 + (-3/4)= I was absent when class learned this, now i am really behind and close to getting an F! Please help me
negative is like go left on the number line adding a negative means keep going left so -4/7+(-3/4) we have to make bottoms same -4/7 times 4/4=-16/28 -3/4 times 7/7=-21/28
we have -16/28-21/28=(-16-21)/28=-37/28=-1 and 9/28
