Ned's frog jumped 38/100 meter. Then his frog jumped 4/10 meter. How far did Ned's frog jump in all?

78/100 meter because 1/10 = a tenth = 10/100. So 4/10 = 40/100 so I added 40 and 38 x

So first, we need to find a common denominator, make the numbers below the line equal to each other

to do this, we multiply the denominator AND numerator of 4/10 so you can get the equivilent fraction with a denominator of 100

4*10=40

10*10=100

4/10=40/100

now we add the two fractions together and we get

38/100+40/100=

78/100 of a meter
