Gerard and Martin were both given a pay rise. Gerard was given a 25% pay rise and Martin was given a 5% pay rise. The ratio of Gerard’s salary to Martin’s salary is now 12:7. Martin is now paid £21000. Work out Gerard’s pay before the pay rise

£28,000

Step-by-step explanation:

Martin’s salary is 7/12 of Gerard’s salary. So, you have to multiply by the reciprocal, which is 12/7.

×21,000 = 12×3000=36,000

Since Gerard salary was multiplied by 5/4, multiply by 4/5.

×36,000 = 4×7200=28,000

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
