What is the estimate answer and the exact answer of 17/10 ÷2 4/5

1 answer:

8 0

Both 17/10 and 2 4/5 should be rounded up in preparation for this estimation.

17/10 is close to 2 and 2 4/5 is close to 3. Thus, your estimated answer should be
2/3, or approx. 0.6666....

Exact answer: divide 17/10 by 14/5. LCD is 10, so convert 14/5 to 28/10.

Now divide 17/10 by 28/10. Answer: 17/28 = approx. = 0.607 approx.

These two results are comparable: 0.6666.... and 0.6071 ....

Phantasy [73]

Answer:

Mark gets £54

Step-by-step explanation:

Let Gavin share=x

Henry=3x

Mark=2(3x)

10x=£90

x=9

Gavin=x=£9

Henry=3x

=3(9)=£27

Mark=2(3x)

=2(3*9)

=2(27)

=£54
