Step-by-step explanation:

x : y = 4 : 5 = 4/5 : 1, [Dividing each term by 5]

y : z = 6 : 7 = 1 : 7/6, [Dividing each term by 6]

In both the given ratios, the quantity y is common, so we have made the value of y same i.e., 1.

Thus; x : y : z = 4/5 : 1 : 7/6

= (4/5 × 30) : (1 × 30) : (7/6 × 30), [Multiply all the terms by the L.C.M. of 5 and 6 i.e., 30]

= 24 : 30 : 35

Therefore, x : y : z = 24 : 30 : 35

Answer 2

Answer:

x = 5/4 or 1.25

Step-by-step explanation:

5/4 -4/5 = -4/5 +x

5/4 -4/5 +4/5 =x

x= 5/4

x= 1.25
