Answer 2

I understand that you have some urgent mathematical calculations that you need assistance with. Let's go through each of the problems step by step:

#1a) Find the product of: 1 whole * 1/2 * 3 whole * 2/5 * 4 whole * 1/7 * 7/16

To solve this, you can multiply the fractions and the whole numbers separately:

1 whole * 3 whole * 4 whole = 12 whole (1/2 * 2/5 * 1/7 * 7/16) = (1/2 * 1/5 * 1/7 * 1/2) = 1/140

Now, multiply the whole number and the fraction:

12 whole * 1/140 = 12/140 = 3/35

So, the answer to 1a) is 3/35.

#1b) Perform the division: 2/27 ÷ 1 whole 1/3

To divide fractions, you can multiply by the reciprocal of the divisor:

2/27 ÷ 1 whole 1/3 = 2/27 * 3/4

Now, multiply the fractions:

(2/27) * (3/4) = (2 * 3) / (27 * 4) = 6/108 = 1/18

So, the answer to 1b) is 1/18.

#2a) Find the value of the expressions: (11/15 * 25/33) + (1 whole 3/4)

First, multiply the fractions:

(11/15 * 25/33) = 275/495

Now, add the whole number and the fraction:

(275/495) + (1 whole 3/4)

To add these, convert the whole number to a fraction with the same denominator:

(275/495) + (4/4 + 3/4)

Now, add the fractions:

(275/495) + (7/4)

To add these, find a common denominator:

(275/495) + (1735/990)

Now, add the fractions:

(275/495) + (1735/990) = 5445/4950 = 1815/1650 = 363/330

So, the answer to 2a) is 363/330.

#2b) Find the values of the expressions: (1/2 * 1 whole 2/3) ÷ 10

First, multiply the fraction and the whole number:

(1/2 * 1 whole 2/3) = (1/2 * 5/3) = 5/6

Now, divide by 10:

(5/6) ÷ 10 = 5/60 = 1/12

So, the answer to 2b) is 1/12.

I hope these solutions help you with your urgent calculations! If you have any more questions or need further assistance, please feel free to ask.
