400

Round to the nearest hundredths place

389.498

answer... 389.5

the hundreths place is the second place value to the right of the decimal.

the 8 in the thousandths place tells the 9 to go up. We then have to carry that over into the tenths place.

400

What is

2/10 x 4/6 simplify if needed

answer 2/15

when we are multiplying fractions we just multiply straight across with the numerators and the denominators

2 x 4 = 8

10 x 6 = 60

both numbers are even and can their Greatest Common Factor (GCF) if 4. This means we can divide both numbers by 4 to get our fraction in its simplest form.

500

Round to the nearest whole number

345.432 + 234.465

answer... 580

the sum of the two numbers is 

579.897

the nearest hole number is the ones place; which is the first place value to the left of the decimal. the 8 in the tenths place tells the 9 in the ones place to go up. We then have to carry that over into the tens place.

500

What is 

4/3 + 5/6 simplify if needed

answer... 13/6

The Least Common Multiple (LCM) for the denominators is 6. 

In order to convert the first fraction we must multiply the numerator and denominator by 2.

This turns the first fraction into 8/6 and now we can add the numerators. 13/6 is in its simplest form.

500

A baker used 2/5 of a cup of flour for a cake and 1/3 of a cup of flour for cookies. How much flour did they use in total for both the cake and cookies?

  • To solve this, you need to add the two fractions: 2/5 + 1/3.
  • Find a common denominator (the least common multiple of 5 and 3 is 15):
    • (2/5) * (3/3) = 6/15
    • (1/3) * (5/5) = 5/15
  • Add the numerators while keeping the common denominator: 6/15 + 5/15 = 11/15
