Use a model to divide. 1/4 ÷ 5

Step-by-step explanation:

Any number can be converted to fraction if you use 1 as the denominator:

5

1

So now that we've converted 5 into a fraction, to work out the answer, we put the fraction 1/4 side by side with our new fraction, 5/1 so that we can multiply those two fractions.

That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:

1 x 5

4 x 1

=

5

4

As you can see in this case, the numerator is higher than the denominator. What this means is that we can simplify the answer down to a mixed number, also known as a mixed fraction.

To do that, we need to convert the improper fraction to a mixed fraction. We won't explain that in detail here because we have another article that already covers it for 5/4. Click here to find out how to convert 5/4 to a mixed fraction.

The complete and simplified answer to the question what is 1/4 of 5 is:

1 1/4

Hopefully this tutorial has helped you to understand how to find the fraction of any whole number

d

step-by-step explanation:

d

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
