Lesson 1: Number line- Powers of 10- Forms of a Number

The abscissa of the green point is:

• 7.16

• 7.88

• 7.8

If the boundaries of a number line are in the hundredths place value, then the abscissa of the points between them should be:

• whole numbers

• in the tenths place value

• in the thousandths place value

The standard form of Thirty two million, Two hundred six and seven hundredths is:

• 32,206.07

• 32,000,206.700

• 32,000,206.07

The expanded form of 56,023.047 is:

• $5\ \times\ 10^{4\ }+\ 6\ \times\ 10^{3\ }+2\ \times10\ +\ 3\ +\ 4\ \times\frac{1}{10^2}+7\ \times\frac{1}{10^3}\$

• $5\ \times\ 10^{4\ }+\ 6\ \times\ 10^{3\ }+2\ \times\ 10^2\ +\ 3\ +\ 4\ \times\frac{1}{10^2}+7\ \times\frac{1}{10^3}\$

• $5\ \times\ 10^{4\ }+\ 6\ \times\ 10^{3\ }+2\ \times\ 10\ +\ 3\ +\ 4\ \times\frac{1}{10}+7\ \times\frac{1}{10^3}\$

The standard form of:

 $7\ \times\ 10^6+\ 6\ \times\ 10^{5\ }+2\ \times\ 10^3\ +\ 9\ \times10\ +8\ \times\frac{1}{10^3}\$  

• 762,090.008

• 7,602,090.0008

• 7,602,090.008

36.982 when rounded to the nearest _______ it becomes 36.98

• hundredths

• tenths

• thousandths

312.79 is between the two nearest whole numbers:

• 311 and 313

• 312.7 and 312.8

• 312 and 313

 $36.002\ \times10^2$  

• 36.2

• 3600.2

• 0.36002

 $78.5\ \times0.01\ =$  

• 0.785

• 78.5001

• 78.5

 $326\ \div\ 10^4$  

• The quotient will be greater than 326

• The quotient  will be smaller than 326

• The quotient will be equal to 326
