5) 20 gallons of water was shared equally among 6 families. How many gallons of water did each family get?

3 1/3 gallons

Step-by-step explanation:

There are 20 gallons and 6 families. We want to divide the 20 gallons equally amongst the 6 families. The key word here is "divide". We want to use division:

20 gallons ÷ 6 families = 20/6 gallon per family = 10/3 gallons per family

= 3 gallons per family

Thus, each family got 3 1/3 gallons.

Hope this helps!

3⅓ gallons per family

Step-by-step explanation:

20/6 = 10/3

= 3⅓

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
