87/27 39/11 98/24 88/12 56/45 51/13 211/36 19/3 25/4 10/45 312/56

Answer 1

87/27=3  6\27=3 2\9
39/11=3 6\11
98/24= 4 2\24=4 1\12
88/12= 7 4\12= 7 1\3
56/45=1 11\45
51/13= 3 12\13
211/36=5 31\36
19/3= 6 1\3
25/4=6 1\4
10/45  не получится 10<45
312/56=5 32\56= 5 4\7

мы делим числитель на знаменатель(частное-это целая часть,остаток -в числитель)    например 25:4= 6 остаток 1
25\4=6 1\4

Answer 2

To calculate the sum of the given fractions, we need to find a common denominator and then add the fractions together. Let's go step by step:

1. Convert all the fractions to have the same denominator. To find a common denominator, we can use the least common multiple (LCM) of the denominators.

The denominators in the given fractions are: 27, 11, 24, 12, 45, 13, 36, 3, 4, 45, and 56.

The LCM of these numbers is 27720.

2. Now, let's convert each fraction to have a denominator of 27720:

- 87/27 = (87 * 1024) / (27 * 1024) = 88704/27720 - 39/11 = (39 * 2520) / (11 * 2520) = 98280/27720 - 98/24 = (98 * 1155) / (24 * 1155) = 113190/27720 - 88/12 = (88 * 2310) / (12 * 2310) = 203280/27720 - 56/45 = (56 * 616) / (45 * 616) = 34736/27720 - 51/13 = (51 * 2136) / (13 * 2136) = 108936/27720 - 211/36 = (211 * 770) / (36 * 770) = 162170/27720 - 19/3 = (19 * 9240) / (3 * 9240) = 175560/27720 - 25/4 = (25 * 6930) / (4 * 6930) = 173250/27720 - 10/45 = (10 * 616) / (45 * 616) = 6160/27720 - 312/56 = (312 * 495) / (56 * 495) = 154440/27720

3. Now that all the fractions have the same denominator, we can add them together:

(88704 + 98280 + 113190 + 203280 + 34736 + 108936 + 162170 + 175560 + 173250 + 6160 + 154440) / 27720

= 1,251,456 / 27,720

4. Simplify the fraction, if possible:

The greatest common divisor (GCD) of 1,251,456 and 27,720 is 48.

= (1,251,456 / 48) / (27,720 / 48)

= 26,070 / 575

So, the sum of the given fractions is 26,070 / 575.

Please note that the above calculations were done using the given fractions and their corresponding denominators.
