Answer:
In decimals A= 7.25 , B = 6.75 , C=5.2 and D=6.1
Step-by-step explanation:
Given : Tom works part-time at a theme park.
Tom needs to complete his time sheet in decimals.
Consider the time sheet as shown below in image attached,
We need to calculate the value of A , B, C and D in decimals.
Since, A , B, C and D denotes the total work Tom Jackson did on respective days.
Thus, A is the total hours Tom Jackson worked along with the part-time hours he worked.
A= hour worked + fraction hour worked
\(A=7+\frac{1}{4}\\\\\\\text{Taking LCM , we get}\\\\\ A=\frac{28+1}{4}=\frac{29}{4}=7.25\)
Similarly for B, C and D
B= hour worked + fraction hour worked
\(B=6+\frac{3}{4}\\\\\\\text{Taking LCM , we get}\\\\\ B=\frac{24+30}{4}=\frac{27}{4}=6.75\)
C= hour worked + fraction hour worked
\(C=5+\frac{1}{5}\\\\\\\text{Taking LCM , we get}\\\\\ C=\frac{25+1}{5}=\frac{26}{5}=5.2\)
D = hour worked + fraction hour worked
\(D=6+\frac{1}{10}\\\\\\\text{Taking LCM , we get}\\\\\ D=\frac{60+1}{10}=\frac{61}{10}=6.1\)
Thus, In decimals A= 7.25 , B = 6.75 , C=5.2 and D=6.1
