Solution

3)

a) we need to write the given number in expanded form (elementry schhol type)

we have a number 59,782

we can write the number as 59,782 = 59,000 + 700 + 80 + 2

we can say that the number is Fifty Nine thousand Seven hundred Eighty Two

b)

we need to write the given number in expanded form(using exponents)

we have a number 4,327,986

we can say that 4,327,986 = 4*10⁶ + 3*10⁵ + 2*10⁴ + 7*10³ + 9*10² + 8*10 + 6

we can say that the number is Forty Three lac Twenty Seven thousand Nine hundred Eighty Six

4)

we need to round the given number to the nearesr given place value.

we have a number 547,931,402

a)

we have to round 547,931,402 to the nearest million

First looks to the right of millions place that is at hundred thousands place

we have 9 at hundred thousands place which is > 5

Hence we can round 547,931,402 to 548,000,000

b)

we need to round 547,931,402 to nearest thousand

First looks to the right of thousands place that is at hundreds place

we have 4 at hundred place which is < 5

Hence we can round 547,931,402 to 547,931,000

c)

we need to round 547,931,402 to nearest ten millions

First looks to the right of 10 millions place that is at millions place

we have 7 at millions place which is > 5

Hence we can round 547,931,402 to 550,000,000

d)

we need to round 547,931,402 to nearest hundred thousand

First looks to the right of hundred thousand place that is at ten thousands place

we have 3 at ten hundred place which is < 5

Hence we can round 547,931,402 to 547,900,000
