EQUIVALENT FRACTIONS

PROBLEMS

Do the problem yourself first!

 1.  Write three fractions that are equivalent to 58 .
 For example: 1016 1524 2032

Multiply both 5 and 8 by the same number.

2.  Write the missing term.

 4.   a) 23 = 8 12 4.   b) 45 = 1215 4.   c) 34 = 1520 4.   d) 29 = 1254 4.   e) 78 = 3540 4.   f) 56 = 3542 4.   g) 27 = 8 28 4.   h) 516 = 1548 4.   i) 34 = 2432 4.   j) 23 = 2030 4.   k) 35 = 2745 4.   l) 35 = 1220 2.   m) 79 = 4254 2.   n) 23 = 1421 2.   o) 89 = 5663 2.   p) 67 = 4856
 3 Convert both fractions to a common denominator.
 3. (What common denominator should you choose?) Since the given denominators have no common divisors, choose the product of the denominators.
 3 a) 12 and 35
 3.  a) 12 = 5 10 , 35 = 6 10 .
 3 b) 23 and 34
 3.  b) 23 = 8 12 , 34 = 9 12 .
 3 c) 57 and 49
 3.  b) 57 = 4563 , 49 = 2863 .

4.  How can we know when two fractions are equivalent?

Their numerators and denominators are in the same ratio.

5.  Write the missing term.

 2.   a) 515 = 7 21 2.   b) 416 = 3 12 2.   c) 321 = 4 28 2.   d) 840 = 3 15 2.   e) 654 = 4 36 2.   f) 12 = 6 12 2.   g) 12 = 48 2.   h) 12 = 5 10 2.   i) 13 = 4 12 2.   j) 14 = 3 12 2.   k) 15 = 6 30 2.   l) 216 = 3 24 2.   m) 735 = 4  20 2.   n) 816 = 5 10 2.   o) 330 = 7 70 2.   p) 545 = 2 18

6.  Reduce each fraction to lowest terms.

 16. a) 812 = 23 16.  b) 36 = 12 16.  c) 515 = 13 16.  d) 1624 = 23
 16. e) 2163 = 13 16.  f) 2035 = 47 16.  g) 1254 = 29 16.  h) 648 = 18
 16. i) 6381 = 79 16.  j) 1560 = 14 16.  k) 1636 = 49 16.  l) 2472 = 13
 16. m) 3040 = 34 16.  n) 600900 = 23 16.  o) 50 400 = 18 16.  p) 1800  12,000 = 3 20
 16. q) 33 = 1 16.  r) 1818 = 1 16.  s) 527 527 = 1 16.  t) 12,308  12,308 = 1

7.  Write as a mixed number.

 17. a) 12 8 = 1½ 17. b) 34 6 = 5 23 17. c) 3616 = 2¼ 17. d) 2820 = 1 25
