How many grams is 2000 kg minus 500 grams

1000500g

2000 times (1 minus 1 / 4 equals 1)?

It's 1500

How many minutes is 0.25

15 minutes

How many minutes is 0.6

6 hours = 0.6x60 = 36 minutes

What is 100 times 5 minus 100

100

X plus 5 divided by 6 times 7 minus 5 equals 100. What's x

Inverse method
（100+5）/7*6-5=85

The arithmetic square root out of 5 is 3, and the arithmetic square root out of 3 is 2, which is bigger

Both sides square at the same time, and then there is a simple comparison of two fractions

Move a matchstick so that equation 5-3 = 12, 17-21 = 4 holds
I'm sorry, but I didn't make it clear.

Take the 1 of 12 to the upper right corner of 2 in the form of exponent, and then take a match to the minus sign

Move a match to make the equation 12 + 22 + 17 = 7

Move the cross of the second plus sign to the right so that the right side becomes 17
The equation becomes 12 + 22-17 = 17
It is solvable

12-4-3 = 17 move a match to make the equation true

12 - 4 + 3 = 11 move the top of 7 to the left - sign and change to the + sign
