Calculations

1) 11/15*21/20*9/28*8/9

To solve this expression, we can simply multiply the given numbers together:

11/15 * 21/20 * 9/28 * 8/9 = 0.047619047619047616

So, the result of the expression 11/15*21/20*9/28*8/9 is approximately 0.0476.

2) 2+1/2*3+1/3*+4+1/5*8/35

To solve this expression, we can follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right):

2 + 1/2 * 3 + 1/3 * 4 + 1/5 * 8/35 = 2 + 1.5 + 1.3333333333333333 + 0.45714285714285713 = 5.290476190476191

So, the result of the expression 2+1/2*3+1/3*+4+1/5*8/35 is approximately 5.2905.

3) 3/8*1+5/7*4/9*2+1/3

To solve this expression, we can simply perform the arithmetic operations:

3/8 * 1 + 5/7 * 4/9 * 2 + 1/3 = 0.375 + 0.31746031746031744 + 0.3333333333333333 = 1.0257936507936507

So, the result of the expression 3/8*1+5/7*4/9*2+1/3 is approximately 1.0258.

4) 1+4/5*1+2/3*2+1/7*4+2/3

To solve this expression, we can perform the arithmetic operations:

1 + 4/5 * 1 + 2/3 * 2 + 1/7 * 4 + 2/3 = 1.8 + 1.3333333333333333 + 0.5714285714285714 + 0.6666666666666666 = 4.371428571428571

So, the result of the expression 1+4/5*1+2/3*2+1/7*4+2/3 is approximately 4.3714.
