Question

3/10 - (3 - 2 33/35) : 5/14- 1 1/5

Answer 1

3/10-(3-2 33/35):5/14-1 1/5= -1  3/50

3-2 33/35=3-103/35=105/35-103/35=2/35

2/35:5/14=2/35*14/5=28/175

3/10-28/175=525/1750-280/1750=245/1750=49/350=7/50

7/50-1 1/5=7/50-6/5=7/50-60/50=-53/50= -1  3/50 ну как то так получилось

Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's break down the expression step by step:

1. Start with the parentheses: (3 - 2 33/35) = 3 - (2 + 33/35) = 3 - (70/35 + 33/35) = 3 - (103/35)

2. Perform the division first: 3 - (103/35) = (3 * 35)/35 - (103/35) = (105/35) - (103/35) = (105 - 103)/35 = 2/35

3. Next, let's deal with the subtraction on the left side of the main division: 3/10 - (2/35) = (3 * 7)/ (10 * 7) - (2/35) = 21/70 - (2/35)

4. Now, find a common denominator for the right side of the main division: 21/70 - (2/35) = 21/70 - (4/70) = (21 - 4)/70 = 17/70

5. Finally, move to the right side of the main division and work on the subtraction first: 5/14 - (6/5) = (5 * 5)/(14 * 5) - (6/5) = 25/70 - (42/70)

6. Combine the fractions on the right side of the main division: 25/70 - (42/70) = (25 - 42)/70 = -17/70

So, the final answer to the expression is: (17/70) / (2/35) = (17/70) * (35/2) = (17 * 35) / (70 * 2) = 595 / 140 = 85/20 = 17/4 or 4.25
