How do you know that 1.016 divided by 4.064 equals 0.025 without doing the division

Answers

Answer 1
Answer:

Answer:

We have to find the value of (1.016)/(4.064) without division.

We have to convert  (1.016)/(4.064) into simplest form

To convert into simplest form, Find the hcf of 1.016 and 4.064 and than divide the numerator and denominator by hcf

The hcf of  1.016 and 4.064 is 1016

(1.016)/(4.064) =  (1016)/(4064)

{We can remove the decimals directly if numerator and denominators are like decimals}

Divide Numerator and denominator by 1016

(1016 divide by 1016)/(4064  divided by 1016)

(1)/(4)=0.25

The answer is 0.25

Hence we get 0.25 without by actual division.

Answer 2
Answer: When you round each value to a whole number, it will equal 1/4 (a fourth) which is then simple math. (1/4=0.25)

A cyclist rode 1 mile at full speed in 3 minutes with the wind and returned in 4 minutes against the wind, again pedaling at full speed. Find his speed without the wind. ("Challenge" question)

Answers

so 1 mile per 3 minute or
1 times 20=20
3 times 20=60

20 miles in 60 minutes or
20 miles per hour

20 mph with wind

4 mins agains the wind
multiply 15
15 miles per hour agains the wind


so d=st

distances are the same
d=st
20mph with the wind
20=wind+real speed

15mph agains the wind
15=real speed-wind

20=w+rs
15=-w+rs
add together
35=2(rs)
divide 2
real speed=17.5

Ans.5) you can re-write 3 3/10 as 33/10

Now, you have to find two numbers whose sum would be 33/10.

Try to fix the denominator, and change numerator...like

it would be 13/10 + 20/10 or 15/10 + 18/10.Ok..
