What numbers do you multiply to get 900?
90x10=900
90 is 10 percent of what number?
90 is 10% of 900. 90x10=900
30 percent of what number is 90?
Answer 300 ---- Here is why: This is the same as asking .3x=90 so the number is 90/.3 =300 Note, 90/.3 is 90 divided by 3/10 which is 90x10=900 divided by 3.
60 x 15?
900. I noticed that if you divided 60 by two, and multiplied 15 by two, you would get 30 on both accounts. You could go even simplier and times 30 by 3, and divide 30 by three, which would make the equation 90x10. Soooo simple, but I knew that 3x3 equals 9, so I knew that the first part of the answer was 9, then I added the two left over noughts to the answer, which means I got 900. NOTE: The adding the zeros to the end of the answer ONLY works if both of the numbers you need to multiply have a zero in the one's column.

What is the number 90 10?
the answer is 100 this is wen wen from o.e.d (old east dallas) i just want to say hy to all em cribs out theri love you jr my bro Also, it could depend on what you're asking. Are you asking...? 90+10= 100 90-10=80 90x10=900 90 divided by 10=9 90 and 10 written out= ninety and ten 90.10 written out=ninety and ten hundredths (which can be simplified as ninety and one tenth) 9,010 written out= nine thousand, ten I'd recommend including a some sort of sign, whether it be a decimal, comma, addition sign, subtraction sign, multiplication sign, or division sign.
How long can a cactus go without water in the desert?
Some cacti can survive for several years without water in the desert due to their ability to store water in their stems. The exact amount of time varies depending on the species of cactus and environmental conditions.
Why are powers of ten important?
Powers of ten are very useful if you understand how 'Indices ' work mathematically. If you want to multiply 2 or more numbers together , without a calculator, you use Logarithms. First you change all your numbers into powers of 10 then you simply ADD the Indices and then convert your result , back into a plain number again. This is all done by using a book of 'Logarithms'. This is how the principle works:- Suppose you wish to multiply 300x5000x60,000 First change the figures to read 3x5x6x100x1000x10000 Now arrange the numbers to read 90 X100x1000x10,000. This can now be written as :- 90 X 10 to power 2 X 10 to power 3 X10 to power 4 . These powers are called Indices. Now add the 3 indices and you have now expressed your quantities as simply 10 to the power2+3+4 which is 10 to power 9 . So now we have 90X10 to power9 and 10 to power 9 is equal to 1000000000 So the answer is 90,000,000,000 Of course we did not need Log. Tables to do this because we already know that 100 is 10 to power 2 but a Log book turns any number you wish, into a power of 10. Example 48 = 10 to power 1.6812(from log book) A book of Logarithm tables allows you to convert any number that you desire, into a power of 10. To multiply 24.5x31.84x73.62 you simply turn these 3 numbers into powers of ten (using a book of Log tables) and add the 3 logarithms , then convert your result back to an ordinary number using Antilogarithm tables. Prior to about 1970 the electronic calculator would cost hundreds of dollars. Engineers and anyone needing to do complex calculations , always used a book of 'Logarithmic Tables' which also had tables of Anti-logarithms.
