Question

How do i work out what 2/5ths of 26 is?

Answer 1

Easy. One 5th of 26 is 26/5 = 5 1/5 (or 5.2).

Multiply by 2 = 10 2/5 (10.4)

Answer 2

Don't just multiply and divide directly, as some suggestions have it.  Let's see if you can cut down the workload by judicious recognition of easier calculations.

First, dividing 5 into 26 is going to leave a remainder, which has to be multiplied again by the 2. Too much like hard work!

Notice that 2/5 is the same as 4/10.  Multiplying 26 by 4 then dividing by 10 is a whole lot easier.

4 times 26 is 2 times 52 is 104.

Divide by 10 to get 10.4.

Easy peasy.  Always look for shortcuts and conversions to make arithmetic life easier.

Answer 3

divide 26 by 5 and multiply by 2

26/5 = 5.2

5.2 x 2 = 10.4

Answer 4

it's 10.4 .......... 26/5 ........... x2

Answer 5

so... do this

it is 26/1 multiply by 2/5

this holds true for all sums like this.

so...this is 2x26 = 52

so...1x5 = 5

so divide 52 by 5

= 10.4

TADA!

Answer 6

2/5ths x 26 = solve(n)

find common denominator and multiply to find n.

Answer 7

You divide by the bottom number of the fraction and multiply by the top number of the fraction.

As an example, for your question do

26

Divided by

5

Times by

2

Which gives you the answer of 10.4

Answer 8

post it as a question on yahoo answers :p :)

Answer 9

Divide by the bottom and multiply by the top! ie. divide 5 into 26 and multiply your answer by 2!  so answer is 10.4!

Answer 10

Get the division over with first!

So

task 1 find one fifth of 26 by dividing 26 by 5.

26 does not divide by 5 'nicely'

use calculator or long division to get the answer of 5.2

task 2 find two fifths by doubling the one fifth answer!

5.2  x2 = 10.4

answer 10.4

Answer 11

Work out what 1 fifth is so divide by 5 = 5.2  and then for the 2 fifths just double and therefore the answer is 10.4

Answer 12

shortcut, some mental math;

just multiply 2/5 x 26; 26 is a whole number, change it to a fraction by adding a 1 as its denominator

2/5 x 26/1 = 52/5

then change the improper fraction to a mixed number;

52/5 = 10 2/5 (5 goes into 50 ten times with a remainder of 2 or  10 and 2/5)

final answer; 10 and 2/5  this is the correct answer because 4/10 can be simplified to 2/5. When you're dealing with fractions, you always have to simplify to the lowest term. So if you're getting 10.4, the 0.4 has to be turned into a fraction, and thus simplified.

Answer 13

You can divide it by 5 to give 1 fifth (5.2) and then times it by two to give two fifths, which is 10.4.

Answer 14

divide by 5 =5.2 so 2/5ths would be 10.4 remember each whole number contains 10 10ths.
