Round 3.4 to the nearest gallons please.

1 answer:

6 0

I'm assuming the 3.4's units are gallons, too. If you're rounding to the nearest whole gallon, that means you're going to have round 3.4 to the nearest whole number. Think about the two whole numbers 3.4 lies between: 3 and 4. Which one of those is 3.4 closer to? That's where you'll want to round.

6*3=18

Triangle:

Add the 6+6 together to get the height of the triangle and subtract the 3 from the 15 to get the base

(12*12) $\frac{1}{2}$
