Question

How do I do 1.5 divided by -2.5? Round to the nearest tenth

Answer 1

Answer:

First, you'll need to remember your place values: To round a number to the nearest tenth , look at the next place value to the right (the hundredths). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.

Answer 2

Answer: -0.6

Method 1: Converting (great for problems with easy-to-convert decimals and fractions)

First you can multiply both numbers by ten to do an easier math problem of 15/-25. We can simplify this fraction to get 3/-5, which when you divide  -0.6.

Method 2: Division (most universal method)

First multiply both numbers by ten to get 15/-25, like in method one. This time, however, we can do the actual division steps to get -0.6.

Method 3: Converting, but in a different way. (also great for problems with easy-to-convert decimals and fractions)

First convert both numbers to fractions. 1.5=3/2, and -2.5=-5/2. Since we are dividing, we must multiply 3/2 by the reciprocal of -5/2, which is -2/5. Multiply 3/2 bye -2/5 to get -6/10, which simplifies to -3/5, which is equal to -0.6.
