Answer 1

5-3/8=1 5/8

5-2 5/9=2 4/9

2/35*21/44 =3/100

9 3/7*1 1/11 =66/7*12/11=72/7=10 2/7

1 1/15*5/16=16/15*5/16=1/3

7/11*2 5/14 =7/11*33/14=3/2=1 1/2

1 2/23*2,07=1 2/23*2 7/100=25/23*207/100=9/4=2 1/4

2 5/8*0,5*5/7*3,2 =2 5/8*1/2*5/7*3 1/5=21/8*1/2*5/7*16/5=3

4 3/13*13/44=55/13*13/44=5/4=1 1/4

Answer 2

To simplify the given expressions, let's perform the calculations step by step:

1. 5-3/8: 5 - 3/8 = 5 - 0.375 = 4.625

2. 5-2 5/9: 5 - 2 5/9 = 5 - (2 + 5/9) = 5 - 2 - 5/9 = 3 4/9

3. 2/35 * 21/44: To multiply fractions, multiply the numerators and denominators separately. (2/35) * (21/44) = (2 * 21) / (35 * 44) = 42 / 1540 Now simplify the fraction: 42 / 1540 = 21 / 770 = 3 / 110

4. 9 3/7 * 1 1/11: To multiply mixed numbers, convert them to improper fractions, then multiply. (9 + 3/7) * (1 + 1/11) = (66/7) * (12/11) = (66 * 12) / (7 * 11) = 792 / 77 Now simplify the fraction: 792 / 77 = 72 / 7

5. 1 1/15 * 5/16: (1 + 1/15) * 5/16 = (16/15) * (5/16) = 5/15 = 1/3

6. 7/11 * 2 5/14: (7/11) * (2 + 5/14) = (7/11) * (33/14) = (7 * 33) / (11 * 14) = 231 / 154 Now simplify the fraction: 231 / 154 = 3/2

7. 1 2/23 * 2.07: (1 + 2/23) * 2.07 = (25/23) * 2.07 = 51.75 / 23

8. 2 5/8 * 0.5 * 5/7 * 3.2: To multiply decimals and fractions, convert mixed numbers to improper fractions. (2 + 5/8) * 0.5 * 5/7 * 3.2 = (21/8) * 0.5 * 5/7 * 3.2 = (21 * 5 * 2 * 16) / (8 * 7 * 10) = 3360 / 560 = 6

9. 4 3/13 * 13/44: (4 + 3/13) * 13/44 = (55/13) * 13/44 = 55 / 44

Final results:

1. 5-3/8 = 4.625
2. 5-2 5/9 = 3 4/9
3. 2/35 * 21/44 = 3/110
4. 9 3/7 * 1 1/11 = 72/7
5. 1 1/15 * 5/16 = 1/3
6. 7/11 * 2 5/14 = 3/2
7. 1 2/23 * 2.07 = 51.75 / 23
8. 2 5/8 * 0.5 * 5/7 * 3.2 = 6
9. 4 3/13 * 13/44 = 55 / 44
