(a)119是68的百分之幾?

119 / 68 * 100% =175%

求下列各題的值。

(b)15分之8的150% 8/15 * 150% = 12/15
(c)180cm的160% 180cm * 160% = 288CM

求下列各題的未知數。

(d)z的124%是186 186 / 124% = 150
(e)$160是$p的175% 160 / 175% = 91.42

(a) 119分之68x100%

(b)15分之8x100%=150%

(c)180x100%=160%

(d)zx124%=186

(e)160xp=175%

(a)119是68的百分之幾?

(a) 119/68 x 100%
= 1.75 x 100%
= 175%

求下列各題的值。

(b)15分之8的150%

(b) 8/15 x 150%
= 8/15 x 3/2
= 4/5

(c)180cm的160%

(c) 180cm x 160%
= 180cm x 1.6
= 288 cm

求下列各題的未知數。

(d)z的124%是186

(d) z x 124% = 186
z = 186/1.24
z = 150

(e)$160是$p的175%

(e) $160/$p x 100% = 175%
160/p = 1.75
160 = 1.75p
p = 160/1.75
p = 160 除 7/4
p = 160 乘 4/7
p = 640/7

希望幫到你 ^^

(a)119/68 *100%=7/4 *100%=175%

(b)8/15 *150%=8 *10%=80%

(c)180cm *160%=18cm*16=288cm

(d)z*124%=186
z=186/124%
=150

(e) 160=p*175%
160/175%=p
640/7=p
p=91 3/7

(a) 119分之68x100%

(b)15分之8x100%=150%

(c)180x100%=160%

(d)zx124%=186

(e)160xp=175%

Can I help you

a)119/68
=1.75 = 1 又3/4 = 175 %
