Question

can you solve these too ? please​

Answer 1

Answer:

Step-by-step explanation:

7. 2/7 of 3/4 = 6/28 which more simplifies to 3/14

and 3/5 of 5/8 is 15/40 which more simplifies to 3/8

For comparism we have many methods but as here the numerators r same we need to check the denominators , the smaller the denominator the greater the number so here 3/8  or 2/14 , here 8 is smaller than 14 so 3/8 is greator

8.Here u just need to multiply 16 and 2  3/4   as 1l=16m so 2  3/4 l=16*2  3/4

2  3/4=11/4  and 16*11/4=44

so Therefore the car will run 44 meters

9.a)3  1/2*1/4=7/2+1/4=7/8

b)6/13*1/7=6/91

11.a)(-18)*(-10)*9 =180*9=1620

b)5*24=120
