The sum of two numbers is 5.036. one number has a 4 in the tenths place and 7 in the thousandths place. The other number has a 1 in the ones place and an 2 in the hundredths place.What are the two numbers.

Answer 1

Find the two numbers that has the sum of 5.036
First number has a 4 in the tenths place and 7 in the thousands
=> x.4x7
The other number has 1 in the ones place and 2 in the hundredths place
=> 1.x2x
=> x.4x7 + 1.x2x = 5.036
=> x.4x7 + 1.x2x = notice that the thousandths place is 7, add 9 to make it 16.
=> x.4x7 + 1.x26 = carry 1, then in hundredths place 2 + 1 + x, find the number to make it 3, since it’s already 3 x = 0
=> x.407 + 1.x29, in tenths place, notice that we already have 4, add 6 to make it 10, then carry 1 to ones place
=> x.407 + 1.629, Now, in ones place, we have 1 + 1 + x, find a number to make it 5. Add 3
=> 3.407 + 1.629 = 5.036
