Answer:
x=1/9
Step-by-step explanation:
You have to answer all of the equations first
-4.8 • 3.2 = -15.36 (negative times a positive is negative)
2 1/4 + (-1 2/5) first find a common denominator, which would be 20
9/4= 45/20
-7/5 = -28/20
since adding a negative is the same as subtracting a positive, you would subtract 45 and 28 which is 17.
17/20 = 1 3/20 (the answer)
turn the fraction into a decimal by dividing the top number by the bottom number, so 17/20 = 0.85
4.92 divided by -3 equals -1.64 (the answer)
-2 3/5 - (-1 2/5)
make them into improper fractions which is -13/5 and -7/5
it stays negative, so the answer is -6/5 or -1.2
so the answer is
-4.8 • 3.2 < 4.2 divided by -3 < -2 3/5 - (-1 2/5) < 2 1/4 + (-1 2/5)
A whole number is a number that does not have a decimal point- e.g. 0, 1 2, 3 etc.
When rounding a number, if the number after the one that is being rounded is greater than 4, the number is rounded up. If not, it remains the same:
6 is greater than 4. Therefore, 0 is rounded up to 1.
0.64 rounded to the nearest whole number is 1
If you would like to know how many gallons do you need for 1 day, you can calculate this using the following steps:
2550 gallons ... 30 days
x gallons = ? ... 1 day
2550 * 1 = 30 * x
2550 = 30 * x /30
x = 2550/30
x = 85 gallons
The correct result would be 85 gallons.
The answer is -5.3. Hope this helps!! :-)
