2.which ratio is greater: 7:8 or 2:3

3.in 25min a train travel 20km.how far will it travel in 5 minutes​

Answer 1

Answer:

1) income=7500

saving=7500-6300=1200

ratio=1200/7500=12/75=4/25=4:25

2)7:8=7/8

2:3=2/3

lcm of 8 and 3 is 24

(7*3)/(8*3) (2*8)/(3*8)

21/24. 16/24

21:24 >16:24

7:8 > 2:3

3)==20/5=4km
