Conversion a mixed number 5 3
8
to a improper fraction: 5 3/8 = 5 3
8
= 5 · 8 + 3
8
= 40 + 3
8
= 43
8
To find new numerator:
a) Multiply the whole number 5 by the denominator 8. Whole number 5 equally 5 * 8
8
= 40
8
b) Add the answer from previous step 40 to the numerator 3. New numerator is 40 + 3 = 43
c) Write previous answer (new numerator 43) over the denominator 8.
Five and three eighths is forty-three eighths
Conversion a mixed number 2 11
12
to a improper fraction: 2 11/12 = 2 11
12
= 2 · 12 + 11
12
= 24 + 11
12
= 35
12
To find new numerator:
a) Multiply the whole number 2 by the denominator 12. Whole number 2 equally 2 * 12
12
= 24
12
b) Add the answer from previous step 24 to the numerator 11. New numerator is 24 + 11 = 35
c) Write previous answer (new numerator 35) over the denominator 12.
Two and eleven twelfths is thirty-five twelfths
Subtract: 43
8
- 35
12
= 43 · 3
8 · 3
- 35 · 2
12 · 2
= 129
24
- 70
24
= 129 - 70
24
= 59
24
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 12) = 24. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 12 = 96. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - forty-three eighths minus thirty-five twelfths = fifty-nine twenty-fourths.
Add up equation 1 and 2 to eliminate b
(a+b)+(-b+c)=3+3 => a+c=6
subtract this new equation from the third equation:
(a+2c)-(a+c)=10-3 =>c=4
plug in c=4 in a+c=6 =>a=2
a+b=3, a=2 =>b=1
$1.80
3.99 x 0.04 = 1.79
and you get 1.80 when you round it
Answer:
Yes, they make sense outside the context of temperature.
Step-by-step explanation:
If you are standing in a line, and mark your current position as 0 then if you take two steps ahead it can be counted as positive and if you take two steps back from your current position it can be counted as negative. The positive and negative can denote your forward and backward movement respectively.
If we denote the growth in companies revenue as positive and dip as negative then it would also make sense. A positive number would mean profit for the company while a negative sign would show loss.
