0.4 = 2/5 as a fraction
To convert the decimal 0.4 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
0.4 = 0.41
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,
0.41 = (0.4 × 10)(1 × 10) = 410.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(4,10) = 2. So,
(4÷2)(10÷2) = 2/5 when reduced to the simplest form.
Answer:
ADB and ABC are similar
x = 8
Step-by-step explanation:
hypotenuse in ADB = 
since two triangles are similar,
solving for x, x=8
Answer:
x = 60°
y = 72°
z = 48°
Step-by-step explanation:
x = 180 - p = 180 - 120 = 60
Since y;z = 3:2 , 2y = 3z or z = 2y/3
Now, x + y + z = 180
60 + y + 2y/3 = 180 Multiply thru by 3 to remove the fraction
180 + 3y + 2y = 540
180 + 5y = 540
5y = 360
y = 72
z = 2(72)/3 = 48
Check: 60 + 72 + 48 = 180
Answer:Each side of x would be 7 and each side of y would be 4.
