50 thousands, 3 hundreds, 7 tens, 2 ones
10
It is 30 (cont 10 3 x)
(50/100) + (3/10) = (50/100) + (30/100) = (80/100) = (8/10) = 4/5
Three to the nearest tens is zero.
10X3 tens in unit form is written: 10*3 tens = 30 tens = 300 units.
430
It is 9*10^3.
3 thousands divided 10 in unit form = 0.3
50 thousands, 3 hundreds, 7 tens, 2 ones
5/10 - 3/10 = 2/10 = 1/5
To round off 321 to the nearest 10, you would first identify the digit in the tens place, which is 2. Since the digit in the ones place is less than 5, you would round down to the nearest 10. Therefore, 321 rounded to the nearest 10 is 320.

let x- unit digit 2x + 1- twice the tens by one x + 2x +1 = 10 x + 2x = 10 - 9 3x= 9 x = 3 therefore : x = 3 2x + 1 = 7 the number is 37. you can try checking it: x + 2x + 1 = 10 3 + 2(3) = 10-1 3 + 6 = 9 9 = 9
The expanded form of 3.4 is 3 + 0.4. In decimal notation, each digit's place value is a power of 10. The 3 is in the tens place, representing 3 * 10, and the 0.4 is in the tenths place, representing 4 * 0.1. Therefore, the expanded form is 3 * 10 + 4 * 0.1.
