James has just sold his motorbike for £1,890. He bought the motorbike for £2,700. What was his percentage loss? %

Usimov [2.4K]

£2.700 - £1890 = £810

£ (money) -------------- percentage (%)
2.700 -------------------- 100
810 ----------------------- x

2700*x = 810*100
2700x = 81000
$x = \frac{81000}{2700}$
$\boxed{x = 30}$

Answer:
Percentage loss = 30%

Alex_Xolod [135]

Answer:

hello :

90 = 15×6

75 = 15× 5

highest common factor of 90 and is 15 because highest common factor of 5 and 6 is 1

90 = 3² ×2×5

75= 5^3

common multiple of 90 and 75 is : 3²×2×5² = 450

90 and 75 both smaller than 100.
