Answer:
the first answer a) 46/45 & b)0
Step-by-step explanation:
1. a)2/15 + 16/18
=2*6+16*5/90 [lcm of 15 and 18 is 90] 16/18 reduce form is 8/9
=12+80/90 so,
=92/90 OR 2/15+8/9[lcm of 15 & 9 is 45]
=46/45 =2*3+8*5/45
=6+40/45
=46/45
b)1/15 - 2/30 2/30 is equal to 1/15 so,
=1*2-2*1/30 OR 1/15-1/15
=2-2/30 =0
=0/30=0
