Answer 2

Let's solve these math problems one by one:

1. 199,999 + 1 = 200,000

2. 500,000 - 157,208 * 1057,208 + 10350 - 156/2900 - 605/576 * 987 * 8

We can simplify this expression by following the order of operations (PEMDAS):

500,000 - 166,224,107,264 + 10,350 - 0.0537931 - 840 * 987 * 8

= -1.64952967 × 10^11

Therefore, the answer is approximately -164,952,967,000.

3. Let's use a proportion to solve the sewing problem:

First seamstress: 3 pillowcases per hour Second seamstress: 2 duvet covers per hour

Let x be the number of duvet covers sewn by the second seamstress.

We know that the two seamstresses worked the same amount of time, so we can set up the following proportion:

3 pillowcases per hour = x duvet covers per hour

x = (3 pillowcases per hour) / (2 duvet covers per hour)

x = 1.5 duvet covers

Therefore, the second seamstress sewed 1.5 duvet covers during the same amount of time it took the first seamstress to sew 12 pillowcases.
