/ symbol is used for division.

/ is same as ÷

Sometimes, fractions are shown as ratio, in which case, : symbol is used.

We can write the fraction $\frac{1}{2}$ as 1/2 or 1÷2 or 1:2

$\boxed{\frac{1}{2} \: = \: 1/2 \: = \: 1 \div 2 \: = \: 1 : 2 }\\$

Find the area of the blue sector(s). The diameter is 14.

pav-90 [236]

The area of the entire circle is pi*(7)^2, or 49pi.

Due to the 90 degree angle, the area of the larger blue sector is

90

------- * 49 pi = 49/4 units^2

360

The area of the smaller blue sector is

48

------- 49 pi = (2/15)(49 pi) = 98 pi/15 units^2

360

The total area of the blue sectors is the sum of 98 pi/15 and 49 pi/4 (units^2):

59 units^2

Sholpan [36]

Answer:

the correct solution has been explained

Step-by-step explanation:

Jackson,s reasoning is incorrect because it should be 8 ones and not 8 tens that would give 64

$\frac{640}{80} = \frac{64}{8} = 8$

Moreover, $\frac{637}{78} is\ not\ equal\ to \frac{640}{8}$

as $\frac{637}{78}= 8.16$

whereas $\frac{640}{80}$ = 8

clearly, both quantities are different
