Step-by-step explanation:
first we have to make the same units in ratios as
75cm:1m25cm
1m=100
1m25cm=125cm
thus now the ratio = 75:125(once units are same they can be cancelled or ignored)
=75/25:125/25
=3:5
now Rs. 10:Rs. 7.50
=10:750/100
=10/750/100
=10*100/750
=1000/750
=1000/250:750/250
=4:3
now the ratios are 3:5 and 4:3 respectively
now 3 is common in Both the ratios therefore
the compound or new ratio=4:3:5
