375 x 12 =
4500
One method of calculating this without a calculator is the following:
(300 x 12) + (70 x 12) + (5 x 12) =
3600 + 840 + 60 =
4500

To find what you need to multiply to get 375, you would need to factorize 375 first. 375 can be factored as 3 x 5 x 5 x 5. So, you would need to multiply 3 x 5 x 5 x 5 to get 375.
1 x 375, 3 x 125, 5 x 75, 15 x 25.
Suppose 60 is 37.5% of x That is the same as saying 60/x = 37.5/100 [PER CENT?!] So 60/x = 375/1000 Invert: x/60 = 1000/375 Multiply both side by 60: x = 60*1000/375 = 160 ie 60 is 37.5% of 160
To find the Least Common Multiple (LCM) of 250 and 375 using prime factorization, you first need to factorize each number. 250 = 2 x 5^3 and 375 = 3 x 5^3. Then, identify the common and uncommon prime factors: 2, 3, and 5. Finally, multiply the highest power of each prime factor together to find the LCM: LCM(250, 375) = 2 x 3 x 5^3 = 1500.
