Answer:
Part a)133.3%
Part b)112.5%
Step-by-step explanation:
Part a) We want to express 2 years as a percentage of 18 months.
Make sure both quantities are of the same units.
1 year =12 months
This means
2 years =24 months.
We want to express 24 months as a percentage of 18 months.
The number that comes after of will be in the denominator.
Part 2)
We want to express 225mm as a percentage of 20cm.
10mm= 1 cm
This means
200mm= 20cm
We want to express 225mm as a percentage of 200mm
It’s addition. Subtracting is how much less
<span>So you have to break it down by steps. For the first one19= h over 3-8. First what's 19+8, which is 27. So if you forget the minus 8 part, the answe has to equal 27. 27 x 3 is 81. So if we plug the numbers in, 19= 81/3 -8 makes sense. For the second one, 5t+8= 43. 43- 8 is 35. What times 5 is 35, that's 7. So plug it in, 5x7 +8 = 43.
Hope it makes sense now!!</span>
