To the left of number 1.
As the 7 is just before the decimal point it is in the units column so its value is 7 × 1 = 7.
7100 = (74)25 As 74 = 7 x 7 x 7 x 7 = 2401 and the units digit of this number is 1 then multiplying this number by itself 25 times would still leave a 1 in the units place. The answer to your question is 1.
When multiplying numbers with the same units digit, the units digit of the product is determined by the units digit of the base number raised to the power of the number of times it is being multiplied. In this case, since 7 is being multiplied 100 times, the units digit of the product will be the same as the units digit of 7^100. The units digit of 7^100 can be found by looking for a pattern in the units digits of powers of 7: 7^1 = 7, 7^2 = 49, 7^3 = 343, 7^4 = 2401, and so on. The pattern repeats every 4 powers, so the units digit of 7^100 will be the same as 7^4, which is 1. Therefore, the units digit of the product when one hundred 7's are multiplied is 1.
Let first number be x Let second number be y x = 7 * 1/2 y x * 2 = 7 * y 2x = 7y x : y = 7 : 2 (simplest form to fit previous line) 7 - 2 = 5 5 units = 35 1 unit = 7 2 units = 14 (answer for y) 7 units = 49 (answer for x)
No, look at your number line, 1 is to the left of 7, so 1 is less than 7.
