To write 150 million in decimal form, you would place the decimal point after the first digit (1) and add the appropriate number of zeros to represent the millions. Therefore, 150 million in decimal form is 150,000,000.
I love these: T = tens place or first digit. U = ones place, units place, or second digit. 10T+U is the first number T+U=15 = T=15-U 10U+T is the number with the digits switched. 10U+T=10T+U+9 10U+15-U=10(15-U)+U+9 9U+15=150-10U+U+9 9U+15=159-9U 18U=144 U=8 T=15-8 T=7
No.
