The reciprocal of false score is less than or equal to 1, is that right? Urgent, teacher help me

yes
Because the numerator of the false fraction is greater than or equal to the denominator
So the numerator of the reciprocal is less than or equal to the denominator
So the reciprocal of false fraction is less than or equal to 1

Choice: () reciprocal must be less than or equal to 1. A true fraction, B false fraction, C decimal

B false fraction, because there are false fractions equal to 1 (the numerator and denominator are the same) and the numerator and denominator are larger than the denominator, the reciprocal is the transposition of the numerator and denominator, which means that the numerator and denominator are equal (i.e. equal to 1) and the numerator and denominator are smaller (i.e. less than 1)

Choice: () reciprocal of true fraction () reciprocal of false fraction () or (). A less than 1. B equal to 1. C greater than 1

A number plus 18 is 50% of 96. Find this number

96×50%-18
=48-18
=30

18 divided by () is equal to 24 parts () is equal to 1.5 is equal to () than () is equal to%

12 16 3 2 150

1 / 3 of a number is equal to 2 times of the sum of 5, which is equal to 18

Some number is X
(1/3*x+5)*2=18
1/3x+5=9
1/3x=4
x=12

There are four rational numbers (- 2) 5 (- 10) 18, which are added, subtracted, multiplied and divided by four operations, and the result is equal to 24

[5+(-2)]×[18+(-10)]=24

A number plus five times that number is 24.6. What's that number

x+5x=24.6
x=4.1

40% of a number plus 12 is exactly equal to the number itself

12 (1-40%) = 12 (60%) = 20 A: this number is 20

Two thirds of a number is equal to two fifths of 40. What is the number

40 × 2 / 5 = 16; 16 △ 3 / 2 = 24
