Answer:
2.86 hours = £26.57
Step-by-step explanation:
5 builders = 3.5 hours
<u>Express it in ratio form:</u>
5 : 3.5 (B1:H1)
<u><em>However, on Tuesday 2 builders(B2) are available. We can set up a proportion to find the number of hours.</em></u>
<u><em>Since This is an inverse proportion, it will be written like:</em></u>
=> B1:H1 = H2:B2
Where H2 = x(no. of hours)
=> 5 : 3.5 = x : 2
<u><em>Product of means = Product of Extremes</em></u>
=> 5*2 = 3.5x
=> 10 = 3.5 x
Dividing both sides by 3.5
=> x = 2.86 hours
<u><em>Now, On Tuesday:</em></u>
1 hour = £9.3
<u><em>For 2.86 hours,</em></u>
2.86 hours = £9.3 × 2.86
2.86 hours = £26.57
The reciprocal of 5/6 is 6/5 because the reciprocal is the numbers flipped around. For an example -5 thr reciprocal will be +5
3 1/2
