① Master Wang processes a batch of parts. On the first day, he processes 1 / 5 of all the parts. On the second day, he processes another 70 parts. At this time, the ratio of processed parts to unprocessed parts is 3:2. How many parts are there in total? ② There are two baskets of eggs. The number of eggs in basket a is 18 less than that in basket B. if six of them are taken out of basket a and put into basket B, the number of eggs in basket a is 4 / 7 of that in basket B. how many eggs are there in basket a and basket B
Do you know the equation?
If yes, there are x parts in the first question
Then (x / 5 + 70) / x = 3 / (3 + 2)
The solution is x = 175
Suppose there are x eggs in basket a, then there are x + 18 eggs in basket B
Then X-6 = 4 (x + 18 + 6) / 7
There are 46 in a and 64 in B for x = 46
I'll tell you something else
Master Zhang makes a batch of parts in three days, one third of the total in the first day, one fourth in the second day and 25 in the third day. How many parts are there?
25 ÷ (1-1 / 3-1 / 4) = 60
There are 60 parts in this batch
Master Wang made a batch of parts in three days. On the first day, he made 1 / 3 of the total number of pullers. On the first day and the second day, he made 57,
A total of 63 pieces were made on the first day and the third day. How many pieces are there in this batch?
57+63=120
It's twice the sum of day one and day two and day three
And because the second day + the third day is two-thirds of the total
So let's do X on the first day
2X + 2x = 120, x = 30, so there are 30 / 1 / 3 = 90 parts in total
Master Wang plans to make a batch of parts. On the first day, he makes 47 of the planned parts, and on the second day, he makes the remaining 35. At this time, there are still 42 parts left. How many parts does Master Wang plan to make?
Mr. Wang plans to make 245 parts
