905 = 9 hundreds + 0 tens + 5 ones
or 8 hundreds, 10 tens, 5 ones
425 = 4 hundreds, 2 tens, 5 ones
8 hundreds, 10 tens, 5 ones
4 hundreds, 2 tens, 5 ones
---------------------------------------subtract
4 hundreds, 8 tens, 0 ones = 480......(905 - 425 = 480)
His reasoning is not valid because they might actually appear to be equal to his sight, but should he measure them they might not exactly be.
So he just can't look at it and conclude. He can say it is equilateral if each angles measures 60 degrees.
Answer:
Decrease number 30 by 10% of its value: New value = 30 - Percentage decrease = 30 - (10% × 30) = 30 - 10% × 30 = (1 - 10%) × 30 = (100% - 10%) × 30 = 90%
Step-by-step explanation:
The answer to this question is 7 4/9
to find this you first have to find the LCM (in this case it is 9) then you have to figure what you multiplied by to get to your LCM (9) whatever you do to the bottom you have to do to the top and that is how you end up with your numerator (the top number in a fraction) usually if you have the same denominators (the bottom number in a fraction) you can +/- like normal. sometimes though you can't (like this case) because you can't take a bigger number away from a smaller one.
