Question

a) -4 + 2 + (-1) + (-3) – 4​

Answer 1

Answer:

-10 is your answer

Step-by-step explanation:

-4 + 2 + (-1) + (-3) – 4

= - 4 + 2 - 1 - 3 - 4

= -10

Answer 2

Answer:

To find a new numerator:

a) Multiply the whole number 2 by the denominator 4. Whole number 2 equally 2 * 4/

4

= 8/

4

b) Add the answer from previous step 8 to the numerator 1. New numerator is 8 + 1 = 9

c) Write a previous answer (new numerator 9) over the denominator 4.

Two and one quarter is nine quarters

Add: 9/

4

+ 3/

4

= 9 + 3/

4

= 12/

4

= 4 · 3/

4 · 1

= 3

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 both denominators - LCM(4, 4) = 4. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 4 = 16. In the following intermediate step, cancel by a common factor of 4 gives 3/

.

In other words - nine quarters plus three quarters = three.
