There are an infinite number of them. Here are a few: 10/14 5/7 60/84 790/1,106
equivalent fractions of 3/21 = 6/42, 9/63, 12/84,...
60/84 = 5/7
7/8, 14/16
To subtract fractions with different denominators, you first have to find the equivalent fractions that have equal denominators. In this case, you can multiply top and bottom of 5/12 by 7 to give 35/84. You can multiply top and bottom of 4/7 by 12 to give 48/84. Thus the question can be rewritten as 35/84 - 48/84. This is just a straight subtraction which gives the answer -13/84
fractions equivalent to: 5 over 7 = 10/14, 15/21, 20/28,... 60 over 84 = 5/7, 30/42, 20/28,...
24/84 = 2/7 in its lowest terms
There are an infinite number of them. Here are a few: 10/14 5/7 60/84 790/1,106
36 over 42 and 72 over 84
There are an infinite number of such fractions: 21/60, 14/40, 7/20, 35/100, 84/240, etc. Just multiply or divide both numbers by any other number and you get an equivalent fraction.
They are: 42/47 and 126/141
equivalent fractions of 3/21 = 6/42, 9/63, 12/84,...
Yes, the fractions 15/28 and 45/84 are equivalent, as 45/84 reduces to 15/28.
42/50, 21/25
Some equivalent fractions of 49/84 are: 7/12 = 14/24 = 21/36 = 28/48
No. If you find the cross products (3 and 84 ..... 14 and 21) and multiply them together, you would get 294 and 252. Since 294 and 252 are not equivalent, the fractions aren't equal.
If you mean 42 then as improper fractions they are 42/1 and 84/2
