Let the number be x
So 12% of x
= 0.12 of x
= 0.12x
Also 10 % of 6
= 0.10 of 6
= 0.10 ×6
= 0.6
Now 12% of x is the same as 10% of 6.
So
Now as both represent the same quantity
So 0.12x = 0.6
Dividing both sides by 0.12
We get
x = 0.6 / 0.12
x= 5
Hence 12% of 5 is the same as 10% of 6
Answer:
£175
Step-by-step explanation:
Given the exchange rate was £1 = 1.84 dollars.
We are to change 322 dollars to pounds (£).
£1 = 1.84 dollars.
x = 322 dollars
Cross multiply
1.84 * x = 322
1.84x = 322
x = 322/1.84
x = 175
Hence 322 dollars in pounds will be £175
