How to subtract -2 1/6-2/3

Conversion a mixed number 2 1/6

to a improper fraction: 2 1/6 = 2 1/6

= 2 · 6 + 1/6

= 12 + 1/6

= 13/6

Multiply the whole number 2 by the denominator 6. Whole number 2 equally 2 * 6/6 = 12/6

To find new numerator: 13/6 - 2/3= 13/6 - 2 · 2/ 3 · 2 = 13/6- 4/6= 13 - 4/6= 9/6= 3 · 3/3 · 2= 3/2

Add the answer from previous step 12 to the numerator 1. New numerator is 12 + 1 = 13

Write a previous answer (new numerator 13) over the denominator 6.

Two and one sixth is thirteen sixths

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(6, 3) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 3 = 18. In the next intermediate step , cancel by a common factor of 3 gives 3/2

.

In words - thirteen sixths minus two thirds = three halfs.

I'm not sure if this is right but if it's not I did math for nothing-.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
