Answer:
<u>The</u><u> </u><u>requ</u><u>ired</u><u> </u><u>num</u><u>ber</u><u> is</u><u> </u><u>7</u><u>0</u><u>.</u>
Step-by-step explanation:
let the no. be 10y + x where x is unit digit and y is ten's digit.
given , sum of the digit is 7
x + y = 7 ...(1)
also , reversing the no. we get 10x + y ,where x is ten's digit and y is unit digit.
given reversed digit decreases the number by 63 .
so, 10y + x - ( 10x + y ) = 63
9y -9x = 63
( dividing both side by 9 )
y - x = 7 ....(2)
adding 1 and 2 [ refer attachment ]
so the required original number is
10y + x = 10×7+0 = 70

Here's how to convert 0.46 to a fraction...
There is not much that can be done to figure out how to write 0.46 as a fraction, except to literally use what the decimal portion of your number, the .46, means.
Since there are 2 digits in 46, the very last digit is the "100th" decimal place.
So we can just say that .46 is the same as 46/100. The fraction is not reduced to lowest terms. We can reduce this fraction to lowest
terms by dividing both the numerator and denominator by 2.
Why divide by 2? 2 is the Greatest Common Divisor (GCD)
or Greatest Common Factor (GCF) of the numbers 46 and 100.
So, this fraction reduced to lowest terms is 23/50
So your final answer is: 0.46 can be written as the fraction 23/50
A) the answer is A) 0 the answer is 0
