Use compatible numbers to estimate the quotient 252÷3

ICE Princess25 [194]

Answer:

The value of the given expression is 84.

Step-by-step explanation:

The given expression is

$\frac{252}{3}$

The number 252 can be written as 240+12, because 24 can easily divisible by 3.

The compatible numbers are 240 and 12

$\frac{252}{3}=\frac{240+12}{3}$

$\frac{252}{3}=\frac{240}{3}+\frac{12}{3}$

$\frac{252}{3}=80+4$

$\frac{252}{3}=84$

Therefore the value of the given expression is 84.

Abigail is 8 years older than Cynthia.Twenty years ago Abigail was three times as old as Cynthia.How old is each now?

xz_007 [3.2K]

Let
C=Cynthia's age today
A=Abigail's age today

then
at all times
A=C+8......................(1)
twenty years ago,
A-20=3(C-20)
simplifying
A=3C-40...................(2)

Equate (1) and (2),
C+8=3C-40
8+40=3C-C
C=24
=>
A=32

Check: A-C=8... ok A-20=12 C-20=4 => (A-20)=3(C-20) ...ok

Answer:
Abigail is 32, Cynthia is 24.
