dont worry about not understanding something! im sure with time and practice youll understand. math may not be your best subject, but youll get the hang of this soon. :')

also, i apologize if this answer is wrong. i havent done this in a while and im not 100% sure on my work accuracy.

Step-by-step explanation:

Count the number of 'x' symbols are above each number.

There are:

two 1/6 pieces (total of 2/6)

two 1/3 pieces (total 2/3)

three 1/2 pieces (total 3/2 aka 1 and 1/2)

four 2/3 pieces (total 8/3 aka 2 and 2/3)

one 5/6 piece (total 5/6)

Since we know that halves and thirds can be divided into sixths, we'll have to set all the denominators into sixths by multiplying. The numbers are in the same order as above.

2/6 * 1/1 = 2/6

2/3 * 2/2 = 4/6

1 and 1/2 * 3/3 = 1 and 3/6 (only multiply the fraction if it is a fraction and a whole)

2 and 2/3 * 2/2 = 2 and 4/6

5/6 * 1/1 = 5/6

Next we'll add together all the WHOLE numbers.

1 + 2 = 3

Now add all the fractions. Remember, only add the numerators, the denominator stays the same in adding.

2/6 + 4/6 + 3/6 + 4/6 + 5/6 = 18/6

Simplify the fraction.

18/6 = 3.

how am i supposed to answer
