Answer:

7. -37/36 or -1 1/36

8. -3/10

9. 1/24

10. -118/21 or -5 13/21

11. 97/12 or 8 1/12

12. 49/8 or 6 1/8

Step-by-step explanation:

To subtract fractions, they must have the same denominator. The common denominator will be the LCM (lowest common multiple) of the two denominators. Then, combine the fractions and simplify.

7. -\frac{1}{4}-\frac{7}{9}  Find a common denominator

=-\frac{1*9}{4*9}-\frac{7*4}{9*4}

=-\frac{9}{36}-\frac{28}{36}

=\frac{-9-28}{36}   Combine the fractions

=\frac{-37}{36}    Answer. Already in lowest terms.

=-1\frac{1}{36} Keep a negative number. 37 goes into 36 one time, leaving 1 remainder (becomes numerator)

8. \frac{3}{5}-\frac{9}{10} Find a common denominator

=\frac{3*2}{5*2}-\frac{9}{10}

=\frac{6}{10}-\frac{9}{10}

=\frac{6-9}{10} Combine the fractions

=\frac{-3}{10} Answer in simplest form.

9. \frac{5}{8}-\frac{7}{12} Find common denominator

=\frac{5*3}{8*3}-\frac{7*2}{12*2}

=\frac{15}{24}-\frac{14}{24}

=\frac{15-14}{24} Combine the fractions

=\frac{1}{24} Answer in simplest form

10. -1\frac{1}{3}-4\frac{2}{7} Translate to improper fraction

=-\frac{4}{3}-\frac{30}{7} Multiplied each whole number with base, added to numerator

=-\frac{28}{21}-\frac{90}{21} Found common denominator

=\frac{-28-90}{21} Combined fractions

=\frac{-118}{21} Answer in improper form

=-5\frac{13}{21} Answer as a mixed number

11. 5\frac{5}{6}-(-2\frac{1}{4}) Convert to improper fraction

\frac{35}{6}-(-\frac{9}{4}) Two minuses make a plus

=\frac{35}{6}+\frac{9}{4} Find common denominator

=\frac{35*2}{6*2}+\frac{9*3}{4*3}

=\frac{70}{12}+\frac{27}{12}

=\frac{70+27}{12} Combined fractions

=\frac{97}{12} Answer as improper fraction

=8\frac{1}{12} Answer as mixed fraction

12. 12\frac{1}{2}-6\frac{3}{8} Convert to improper fraction

\frac{25}{2}-\frac{51}{8}

\frac{25*4}{2*4}-\frac{51}{8} Find common denominator

\frac{100}{8}-\frac{51}{8}

\frac{100-51}{8} Combined fractions

\frac{49}{8} Answer as improper fraction

8\frac{1}{8} Answer as mixed number

aivan3 [116]

Answer:

36

Step-by-step explanation:

after converting the mixed numbers to fractions, our initial equation becomes,

15/4 x 48/5

Applying the fractions formula for multiplication,

15 x 48 and 4 x 5 = 720/20

Simplifying 720/20, the answer is 36
