Show me how to subtract and simplify 4/5 minus 1/9 equals

4/5 = 36/45
1/9= 5/45
then subtract to get 31/45
the simplify

To subtract fractions, you first have to get them to have the same denominators. The least number that both 5 and 9 go into is 45. Multiply 4/5 by 9 to get 36/45, then multiply 1/9 by 5 to get 5/45. Once you get them to have the same denominator, you can subtract the fractions. When you subtract fractions, you subtract the numerators, but leave the denominators. 36-5=31. Once you subtract the numerators, your fraction would become 31/45. To simplify the fraction, you have to find a whole number that goes into both 31 and 45. If there is no number then it is already in simplest form. Your answer would be 31/45.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
